STAF – Linear Guides

As mentioned above, STAF has been in the production of the linear guide since 2007. This factory is able to establish its excellent brand reputation due to its outstanding product quality and services.

Linear guides are widely used in several applications related to linear motion, including automation, precision machinery, medical, semiconductor and transport industries. Other than this, the precision of linear guides earns a big realisation in various high-tech industries like – medical, robotics, and aerospace industries.

Types of Linear Guides

STAF carries a broad range of linear guides. We explain them in detail.

Standard Linear Guides (BGX/BGC)

The standard linear guides are further classified into BGX (non-cage) and BGC (caged). Both linear guides are emphasised with the following features – high efficiency, low noise level, and horizontal smooth motion. One thing that sets STAF linear guides apart from others is the universality of their guide rails with different types of blocks. Under each type of linear guide, there are several sub-types of blocks such as Flanged and Higher assembly height ones. These subtypes are specially designed to use the same rails despite their differences, allowing engineers to replace old blocks without changing the rails.

Shafttech also offers STAF linear guides with custom requirements, including higher precision (H, P), butt-joint applications, parallelism etc. We also provide different types of machining such as rail cutting, additional dowel holes on carriages and anti-rust coating.

BGX (Non-Cage Type) Linear Guide

  • 4-Groove Even Load Design
4-Groove Even Load Design

The four lines of steel balls generate a 45-degree connection with the grooves at four locations. This further helps in stabilising the weight from all areas. As compared to that 2-groove Gothic design, its well-structured design along with 4-groove construction handles the load capacity with more immeasurable rigidity, precision and longevity. Additionally, the auto-adjusting features of the BGX series provide agile and precise linear movements by excluding the assembly failures and others.

  • Seal Design

By and large, the exactness of linear guides relies upon the steel ball rotation between the rail and slide. In many cases, the invasion of external objects can lessen the duration of tracks. It can likewise cause jumping and bumping of the slide, which further drives hard damage. This is the place where the seal design is utilized to improve the exactness of linear guides. The seal design in BGX linear guides is included with two seal systems – upper and bottom seal systems, endeavouring to give an intrusion passageway of the external articles.

  • Oil Retaining in Circulation System

BGX circulation system has the capability of forming a lot more space for storing oil and can also keep it for a longer time. When linear slides move along the rail, the greasing oil will get back to its place that is the oil reservoir in the circulation system.

BGC (Cage Type) Linear Guide

BGC (Cage Type) Linear Guide

The design of the BGC linear guide incorporates a divider between the steel balls. This event happens on the grounds that the outside state of the divider and the manufacturing policies are different, it is hard to totally distribute them all through the circle. The end part may devise a gap of 1 or 1/2 size. But the introduction of a caged system in the BGC linear guide, a linear motion application can get rid of this problem, since it uniformly distributes them in the whole circle. This further gives steadier precision to a significant, long period of time.

Miniature Guides

The cage design and ductile packing system are designed to give the MB series/Miniature tremendous accuracy, low turbulence, and great durability. The STAF miniature guide series, just like the BG series, is also interchangeable with other brands, allowing engineers to switch brands without affecting their pre-designed application. And similar to the BG series, the MB series retains the same universality in rail and block usage. And this is why we are able to provide the same machining services in the miniature series. The miniature guides are further divided into two groups – MBX (non-cage) and MBC (cage) type.

MBX Non-Cage Type

  • Interchangeable to other brands
  • High-precision design
  • Built-in dust sealing structure for Dust-filled environment
  • Versatile Packing System to Guarantee Accuracy
  • Comes in Stainless steel by default

MBC Cage Type

  • Interchangeable to other brands
  • Cage design offers lower noise and boosts shelf-life
  • High-precision design
  • Higher load capacity than MBX types
  • Built-in dust sealing structure for Dust-filled environment
  • Versatile Packing System to Guarantee Accuracy
  • Comes in Stainless steel by default

New Launched Linear Guide Products

1. MPH Retainer Type Miniature Guides

MPH Retainer Type Miniature Guides

This MPH linear guide holds the load evenly in four directions. It’s 2 Gothic arc grooves help in reaching a high accuracy level as it’s in contact with steel balls at 45°. It perfectly balances the load from all directions and provides stabilized mounting orientations.

  • Retainer

The retainer design protects the steel balls from falling off.

  • Smooth Movement

Both the lubrication sponge and the retainer collectively serve high-precision and smooth linear movement.

  • Compact Size

MPH linear guide is most suitable for applications with a very confined area due to its compressed dimension.

2. BGXW Wide Rail Linear Guides

The BGXW Wide Rail Linear Guides provides high accuracy in linear motion, which has a superior dust protection feature. It is inherited from the BG series.

BGXW Wide Rail Linear Guides
  • 4-Way Equal Load and Self-Adjustment Capability

It is featured with four-way Equal Load and self-adjustment capability. The four rows of steel balls generate a 45-degree contact design, enabling the BGW series to be used in all adjustments. Its DF-configuration also gives the highest self-adjustment capability to remove the installation errors and reach a high accuracy level.

  • Optimized Lubrication Path

Equipped with a unique circulation pattern, the lubricating oil provides stable motion. When linear slide transits, it considerably elevates the lubrication capability by evenly spreading the grease without any leakage.

  • High Rigidity and Space Saving

Its wide rail design accommodates the applications with high rigidity against the moment in a single axis configuration. The BGW series is also an ideal choice for applications with limited space.

Proper Installation of Linear Guides

In this section, we’ll explain in detail how to install linear guides in linear type applications.

Step 1: Before mounting the linear guides, a highly recommended advice is to clean up all rough edges and contaminate objects.

Clean up all rough edges

Important: Datum lines of linear guides are normally composed of antirust. So, brush the antirust with a cleanser before positioning. Spraying some low coherence grease can preserve the datum plane.

Step 2: Place the linear guide on the base and secure it with the drive screw or other appliances, so it sits properly on the datum line nicely.

 Place the linear guide on the base

Important: Don’t forget to examine the adjustment of the screw holes before tightening them. Tightening the screw forcefully can unalign the screw holes, which influences the accuracy and quality due to offset.

Step 3: Sequentially fasten the bolts to make the rail more steady. Push the track against the datum line gently to improve the connection between them.

Step 4: Through a torque wrench, tighten the bolts from the centre to both edges.

Step 5: Repeat similar strides for installing the auxiliary rail and then install the slides on the rail independently. Don’t forget to gather all adornments, like lubricant fitting, grease fitting and seals in this stage. Otherwise, later on, it gets hard to gather the adornments because of less space.

Step 6: Locate the table smoothly on the slides on both main and subsidiary rails.

Step 7: Tighten the perpendicular thrust screw to settle the table and attach the table screws in the sequence.

How to Fix Blocks Onto Rails?

Linear guides are supplied with transparent plastic stoppers that function as mini rails to secure the balls from falling off when it’s not into the stable position on the rails.

Arrange the plastic stoppers with the rail and slowly slide the block from the plastic rail onto the actual profile rail. During this process, ensure that the block doesn’t misalign. When the block is successfully transferred onto the profile rail, the plastic rail will be automatically pushed out in the process.

Bottom Line
