Good Value
Solid build for the price. Shipping took a bit longer than expected, but the product itself meets specifications.

Nice Housing
Aluminum is sturdy and light. The seals keep dust out well. Just make sure to align your shafts properly.
Q: Are replacement LM-UU bearings available separately?
A: Yes, standard LM-UU series linear ball bearings are compatible and can be purchased separately if replacements are needed.
Q: Is the bearing pre-lubricated or do I need to add grease?
A: Yes, the linear bearings come pre-greased from the factory. You can add more later if needed.
Q: What is the mounting hole spacing for the SC40 model?
A: Please refer to the technical drawing in the product images for specific hole spacing dimensions per model size.
Q: What shaft tolerance is required for these blocks?
A: We recommend using hardened steel shafts with h6 tolerance for optimal performance and longevity.
Q: Can I use this housing for vertical load applications?
A: Yes, these blocks support vertical loads, but ensure the shaft is properly supported at both ends to prevent sagging.
