Component Specifications

Definition
A linear bearing housing is a structural component designed to securely mount and align linear bearings (such as ball bushings or plain bearings) on guide rods or shafts. It provides mechanical support, maintains proper bearing alignment, protects the bearing from contaminants, and often includes mounting features for integration into machine frames. These housings ensure precise linear motion with minimal friction and wear in applications requiring accurate positioning.
Working Principle
The housing rigidly fixes the linear bearing in position relative to the machine structure, allowing the bearing's internal rolling elements (balls or rollers) to move smoothly along the guide rod. This converts rotational or applied forces into controlled linear motion while distributing loads and preventing misalignment.
Materials
Typically made from aluminum alloys (e.g., 6061-T6 for lightweight applications), cast iron (for high rigidity and damping), or steel (for heavy loads). May include stainless steel for corrosion resistance or engineered plastics for specific environments.
Technical Parameters
  • Sealing Integrated seals or wipers for contamination protection
  • Lubrication Grease fittings or pre-lubricated designs
  • Bore Diameter Matches bearing OD (e.g., 12mm, 25mm, 40mm)
  • Load Capacity Dynamic/static load ratings (e.g., 500N to 20kN)
  • Mounting Type Flange, block, or pillow block
  • Precision Grade Standard or high precision
Standards
ISO 10285, DIN 645

Frequently Asked Questions

What is the difference between a flange-type and block-type linear bearing housing?

Flange-type housings mount vertically to surfaces via side flanges, ideal for space-constrained applications. Block-type housings mount horizontally with base holes, offering stable support for heavier loads.

How do I select the right material for a linear bearing housing?

Choose aluminum for lightweight and corrosion-resistant needs, cast iron for vibration damping and high rigidity, or steel for maximum load capacity. Consider environmental factors like humidity or chemicals.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
