What Distinguishes SR144TLZ1N
The current SKU record identifies a smooth outer-ring profile, Si3N4 Ceramic balls, a Torlon cage and a one-shield configuration. These fields distinguish SR144TLZ1N within our current high-speed bearing records; they do not by themselves confirm handpiece compatibility.
Identification Before Ordering
Confirm the exact SR144TLZ1N marking, P/N GS-A6, Bore / ID, Outer Diameter / OD and width, the smooth outer-ring profile. Also compare the shield or open configuration and any flange, groove or step visible on the removed bearing. A shared dimension does not establish interchangeability. Compatibility must be confirmed for the exact handpiece and turbine or assembly version.
Information to Send for RFQ Review
Send clear front, side and marking photos of the removed bearing, the measured ID, OD and width, and the rotor, turbine or assembly reference when available. We can then review the submitted information for identification and quotation.
