SC8LUU Linear Bearing - for 8 mm shaft, 58 x 31 x 22 mm

Product Overview

• Linear bearing with ball cage for 8-mm shafts
• Flange design with four holes, M4 thread
• Steel balls and steel housing for long-term durability
• Extended design reduces tipping moment with overhangs
• Grease nipple provided for maintenance

Product Description

The linear bearing supports an 8-mm shaft and is used to build guides in machines and automation systems. The ball cage system runs with low friction over the full length of 58 mm. The wide bearing surface and longer housing make the bearing resistant to tipping moments when the shaft is loaded off-center.

The flange design with four M4 threaded holes allows direct attachment to flat surfaces. The compact format fits into confined installation spaces and can be easily installed in carriages and support frames. Steel balls and a steel housing are used, allowing the bearing to remain operational for a long time even under wear.

Typical applications include 3D printers, CNC milling machines in hobby workshops, and robotics projects requiring precise linear motion. The bearing is suitable for both linear axes and lead screw guides. The maintenance-friendly design with a grease nipple enables relubrication during operation.

For operation, the shaft must be precisely machined to an 8 mm diameter. Regularly adding oil or grease prevents premature wear. If contaminated by dust or metal chips, the bearing should be cleaned regularly.

Safety Notice

During movement, hair, clothing, or limbs may become caught. The bearing is intended exclusively for building prototypes and for testing and development purposes. When installed in machines or near electrical installations, safety guidelines must be observed.
