Fafnir M313KCR precision spindle deep groove ball bearing. Brand: Fafnir. Manufacturer Part Number: M313KCR. Bearing Type: Deep groove ball bearing, spindle quality. Series: 300K. Base Number: M313K. Bore Diameter: 65 mm. Outside Diameter: 140 mm. Overall Width: 33 mm. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: Chrome steel. Design Units: Metric. Country of Origin: United States.
313K — the Fafnir 300K spindle deep groove family at 65 mm bore: one row of balls running in a deep radial groove, ground and cased to spindle quality.
CR — Cage Material: Phenolic. Cage Type: Machined, land-riding. A phenolic cage is light, quiet and self-lubricating, and it is what carries the speed rating on a spindle-quality bearing.
P5 — Precision Class: ABEC 5 / P5. Tighter bore, outside-diameter and running-accuracy tolerances than standard class.
Dynamic Load Rating: 102,754 N. Static Load Rating: 59,606 N. Limiting Speed: 2,930 rpm grease; 3,410 rpm oil. Lubricant: grease or oil. A deep groove raceway carries radial load and thrust in both directions from a single bearing, so one unit locates a shaft without an opposing partner. ABEC 5 / P5 tolerances hold the running accuracy a machine-tool spindle or a precision gearbox needs, and the open execution lets the housing supply lubricant directly to the ball complement.
Maximum shaft fillet radius: 2.11 mm. Shaft backing shoulder diameter: 77 mm. Housing backing shoulder diameter: 128 mm. Outer ring to-clear radius: 2.11 mm.
Unit Quantity: 1 Pc. One bearing, complete with inner ring, outer ring, ball complement and cage.
Envelope: ISO 6313, 65 x 140 x 33 mm. Same-envelope, same-class crosses: SKF 6313/P5, FAG 6313-P5, NSK 6313P5, NTN 6313P5, Koyo 6313 P5. Same-envelope standard-class Conrad types, which match on fit and sit a class below on running accuracy: RHP 6313, SNR 6313, MRC 6313, Timken/Fafnir 313K. MPN Variants: M313KCR, M313K-CR, M-313-K-CR, M 313 K CR, 6313 T P5, 313K.
