Comfort First B7001-c-t-p4s-ul Fag Super Precision Angular Contact Ball Bearing 12x28x8mm - Free 2-day Shipping [tDjQI7Yg]

FAG spindle bearings are super precision single row angular contact ball bearings with solid outer and inner rings, ball and cage assemblies and solid window cages. The dimensions are standardised. Due to their very narrow tolerances, the spindle bearings are particularly suitable for applications involving the highest requirements for guidance accuracy, such as bearing arrangements for main spindles in machine tools.

FAG spindle bearings are always designed as universal bearings, which means that:
The bearing rings are of the same width
The projection on both sides of the bearing is of the same size

B = Standard steel balls
70 = Medium series
C = 15 Degree contact angle
T = Laminated fabric cage, guidance on outer ring
P4S = FAG standard better than P4 to DIN 620
U = Single bearing arrangement in any combination
L= Light preload
