Machine Tool Spindle
Spindles are vital to CNC (Computer Numerical Control) machining, lathes, mills, routers, 3D printers, cutters, and grinders. They hold either the working tools or the piece being machined. Mills, additive manufacturing companies, and machine shops all need their machines to work efficiently, often at high speeds and for long spans of time. Ensuring the accuracy and speed of the spindles is essential to maintain product and company standards. An integral part of that quality control comes from the bearings each company uses.
Alpine Bearing carries the best spindle bearings from Barden, FAG, SKF, NTN, GMN, SLF, Nachi, and TPI in a variety of sizes, bores, and contact angles. Buying bearings from reputable manufacturers enables us to distribute them to our customers with confidence.
Angular Steel Ball Bearings
Angular Steel Ball Bearings are precision angular contact bearings, non-separable with outer rings relieved and available with 15° or 25° contact angles. For critical applications these bearings are stocked as universally ground duplex pairs with standard preloads and as single row bearings. A different design for separable, single row bearing series with inner ring relieved and 15° contact angle is also available. Duplex pairs can be mounted back-to- back, face-to-face or tandem depending on the loading expected. Due to high speeds, these bearings usually require phenolic retainers, which have either a stepped or cylindrical pocket design.View Bearings:

Angular Ceramic Ball Bearings
Ceramic balls are 50% lighter than steel balls, and because they are almost perfectly smooth, they exhibit vibration levels 2-7 times lower than conventional steel ball bearings. These bearings also run at significantly lower operating temperatures, and allow running speeds to increase by as much as 25%. Ceramic ball bearings have been proven to last up to 5 times longer than conventional steel ball bearings and lower operating temperatures help extend lubricant lifeView Bearings:

Cylindrical Roller Ball Bearings
Cylindrical rollers distribute loads across a broader surface allowing for high radial load capacity and higher speeds. Single row and double row cylindrical bearings are used primarily for precision machine tools.View Bearings:

Precision Radial Ball Bearings
Precision radial bearings support axial loads in a single direction. They are high rigidity and have a high load capacity. This type of bearing is used for applications requiring high running accuracy and tight dimensional tolerances. Use of nonmetallic retainers such as phenolic can help to achieve higher speeds.View Bearings:

Ball Screw Support Ball Bearings
Ball screw support bearings are designed to provide maximum axial rigidity and improved feeding accuracy for use with precision ball screws. They are high accuracy angular contact thrust bearings which are superior to combinations of standard angular contact bearings or arrangements of radial and thrust bearings for ball screw applications.View Bearings:

Double Direction Ball Bearings
This type of bearing can accommodate axial loads in both directions, and are done in a separable design. Double direction bearings can handily high axial forces and have a high rigidity.
