FAQ

What is the proper lubrication procedure for the UCHP204D1?

The UCHP204D1 comes pre-lubricated from the factory. For relubrication, use a high-quality lithium-based grease and apply it through the grease nipple on the housing until a small amount purges from the seals. Avoid over-greasing as it can cause overheating.

Can this hanger bearing unit handle axial loads?

Hanger bearing units like the UCHP204D1 are primarily designed to support radial loads. They can accommodate light axial loads, but they are not intended for applications with significant thrust forces.

What is the recommended shaft tolerance for a 20mm bore with set screw locking?

For a set screw locking mechanism on a 20mm shaft, a tolerance of h6 or h7 is typically recommended for optimal fit and holding power. Ensure the shaft surface is clean and free from burrs before installation.
