Spindle Bearings
Spindle bearings are very accurately engineered components and as such are very important to the successful performance of the machine tool. With high running accuracy, high-speed performance and high system rigidity, LILY super-precision spindle bearings are ideal for machine tools spindle units. The bearings are designed also to minimize noise, vibration and heat generation.

Handle Machine Tool Spindle Bearings
- Keep your workspace tidy and clean.
- Avoid damage by reducing movement during transport.
- Leave spindle ball bearings in airtight packaging until you begin with their installation.
- Apply axial load only along the marked lines on the outer ring.
- Avoid transmitting assembly forces through the balls.
- Assemble pair bearings of type DB, DF, and DT only with the intended components in the right order. (Universally matched bearings require no particular order.)
- Let spindle ball bearings run in at high rotational speed before putting them into operation.
