NSK Dental drill bearing SR144TLN Dental Handpiece Ceramic bearing 3.175*6.35*2.38mm for high speed handpiece

Dental drill bearing SR144TLN:

Single row deep groove ball bearings are used in a wide variety of applications, they are simple in design, non-separable, suitable for high speeds and are robust in operation, and need little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads.

Detail of Dental drill bearing SR144TLN:

Single row deep groove ball bearings are manufactured as open type (unsealed), sealed and shielded, the most popular sizes of deep groove ball bearings are also produced in sealed versions with shields or contact seals on one or both sides, the bearings with shields or seals on both sides are lubricated for life and are maintenance free. A sealed bearings seals has contact on the bearings inner and outer, a shielded bearings shield has contact on the outer only, and Shielded bearings are primarily intended for applications where the inner ring rotates. If the outer ring rotates, there is a risk that the grease will leak from the bearing at high speeds.

 What is the difference between LLB, LLU & VV seals?
The "LLB" & "VV" seal is a non-contact seal for reduced torque or higher speed requirements. The "LLU" seal is contact seal for better grease contamination control, but the contact friction increases torque and lowers the limiting speed.

"2RS" literally means "Two Rubber Seals"
