For machine tool spindles and other setups that need high rigidity and precise rotation, the NTN HSL series angular contact ball bearing handles combined radial and axial loads in a single direction. MR Industrial Accessories supplies this line to customers throughout the United States and Latin America, and can help you match the right execution to your mounting.

The part number is built from several blocks. The prefix 5S denotes a synthetic cage and lubrication intended for high speed. The 2LA block covers sealing or protection. HSL identifies the precision angular contact series, and the three digits that follow, as in 5S-2LA-HSL910UAD or 5S-2LA-HSL917UAD, set the size. The UAD suffix carries the contact angle, internal clearance and other mounting details. Reading the code this way lets you order the full designation without guessing.

Typical installations include milling, grinding and machining center spindles, boring heads, rotary tables on measuring machines and test equipment. The design keeps friction low at speed, which helps control heat and vibration in automotive, aerospace and die-making work.

When choosing a bearing, check the axial load direction, the internal clearance and the lubrication method. HSL bearings can be mounted in pairs, with preload set to suit the application. The 2LA seal keeps contaminants out and lubricant in, but you still need to confirm the limiting speed. Supports must be aligned, since angular misalignment shortens service life. During mounting, do not strike the raceways directly; use the correct tools to preserve precision.

Precision angular contact bearings from different makers can be interchanged when dimensions, contact angle and clearance agree. NTN, SKF, FAG, NSK and Timken all offer comparable series, yet tolerances and suffixes differ. For a replacement, compare the entire code rather than just the size. If you are unsure, send the original code or the main dimensions and we will point you to the compatible option.
