When a spindle or rotary table has to hold axial position in both directions, the SKF BTW CTN/SPW thrust ball bearing is a common choice. It combines high rigidity with running accuracy, so it suits machine tool spindles, rotary tables and measuring equipment. MR Industrial Accessories LLC supplies this series as part of its SKF bearing range.
Reading the code helps you specify the right part. BTW marks a double-effect thrust ball bearing with a split central ring. CTN tells you the cage is glass fiber reinforced polyamide and the ball grooves are optimized. SPW means the rings received a special treatment for wear resistance and running accuracy. Take the BTW 100 CTN9/SPW33: the extra digits and suffixes set dimensions and tolerances, so always confirm them on the data sheet.
These bearings appear where axial capacity and precision matter: metalworking, automotive and machine tool building. Typical mounts include milling, grinding and machining center spindles, rotary tables on inspection equipment, certain press models, robotics and positioning systems. Because they carry load in both directions, they handle arrangements where the load reverses.
Selection comes down to axial load, speed and environment. The bearings usually ship without integrated seals, so external seals are often fitted to keep out dust and moisture. Use a quality grease for precision bearings, and check axial clearance and alignment at mounting. Poor alignment adds load and shortens service life. Follow the manufacturer's mounting and commissioning instructions.
Similar designations exist from other makers, but they are not always directly interchangeable. Mounting dimensions, tolerances and internal design can differ. When replacing, compare the technical specifications and confirm the bearing meets your load and speed requirements. MR Industrial Accessories LLC can advise on options and compatibility, though the application should be validated with a specialist.
