Bearing, Tapered Roller 30206JR

30206JR Tapered Roller Bearing

The bearing is 30 mm ID, 62 mm OD, and 17.25 mm wide.

This is a tapered roller bearing that can be used to replace the spindle bearings on the mini lathe. It requires two of these bearings to update a mini lathe spindle. 

While on a larger machine tapered roller bearings are recommended, on a mini lathe the RPMs achieved, and lateral forces typically applied may not require this upgrade. Additionally, because tapered roller bearings are not sealed, they may require more regular maintenance and can be more difficult to install and "true" in the spindle housing. HiTorque Mini Lathes use Japanese deep groove sealed ball bearings from NSK. We feel this is the best combination for quality long lasting bearings.

*NOTE: These are high-quality NSK, NTN, Nachi, or equivalent brand, permanently lubricated and sealed bearings.

These bearings are 1.25 mm wider than the standard bearings so you need to change a spacer when you install them.

On a mini lathe with a conventional DC motor, you must reduce the length of the rear spacer by 0.10" (2.5 mm). This is our 1310 Spacer, Spindle 32 mm if you want to modify a spacer before you take your lathe apart.

On HiTorque mini lathes and Micro-Mark 7x16 lathes, you must reduce the length of the rear spacer by 0.10" (2.5 mm). This is our 4041 Spacer, Spindle 11 mm if you want to modify a spacer before you take your lathe apart.
