Bosch Rexroth R102922044 - Linear-SET LSACT-20-DD-G

Applications and industrial environments

The Bosch Rexroth R102922044 LSACT-20-DD-G is a premium-class linear bearing unit designed for demanding industrial applications where precision, compactness and long service life are required. The unit is centred on a shaft diameter of 20 mm and features a tandem aluminium housing with dual linear ball bearing sleeves and full sealing on both sides (DD), ensuring protection against contamination and safe operation even under harsh conditions.

This linear unit meets the needs of automated lines, pick-and-place systems, conveyor modules and compact machine tools. It integrates readily into standard bearing housings or custom mechanical frameworks as a turnkey linear motion module, enabling users to benefit from a ready-built system rather than assembling separate bearings and housing components.

Key advantages & features

• High durability: The tandem configuration enhances load-carrying capability and ensures long life under cyclic motion.

• Compact installation: The 20 mm bore linear unit allows installation in spaces where standard bearing blocks may not fit.

• Full sealing (DD): Both sides of the unit are sealed, making it ideal for industrial applications with dust, humidity or moderate contamination.

• Reduced maintenance effort: The module comes pre-lubricated and designed to operate reliably with minimal intervention—making it a true bearing unit that simplifies assembly and service.

• Versatile integration: Designed to be mounted in standard housing units or directly into machine frames, enabling rapid deployment in production or maintenance scenarios.

FAQ - Frequently asked questions

1. What does the designation “LSACT-20-DD-G” mean?
“LSACT” refers to the linear sleeve series from Bosch Rexroth; “20” denotes the 20 mm shaft diameter; “DD” indicates dual-side sealing; “G” often designates the pre-lubricated version or standard grease applied.

2. Is this unit suitable for heavy-duty industrial use?
Yes. The tandem configuration, sealed housing and industrial materials ensure long life in aplikacje przemysłowe, making it suitable as a bearing unit in drives, conveyors or compact machine installations.

3. Can I mount this in a standard bearing housing?
Yes. Although primarily designed as a stand-alone module, it can also be integrated into standard bearing housings or blocks when system design allows and when proper alignment and mounting are ensured.

4. Does it require additional maintenance before use?
No. The unit arrives pre-lubricated and sealed, so minimal maintenance is required at assembly—reducing service downtime and simplifying installation.

5. What is the delivery time and stock status?
