Fafnir M210KCR spindle deep groove ball bearing. Series: 200K. Base Number: 210K. Bore Diameter: 50 mm. Outside Diameter: 90 mm. Overall Width: 20 mm. Bore Type: Straight. Closure Type: Open. Rolling Elements: Ball. Number Of Rows: 1. Bearing Material: Chrome steel. Design Units: Metric.
M — spindle-quality execution at Precision Class ABEC 3 / P6.
210 — the 200K light dimension series, 50 mm bore, ISO 6210 envelope.
K — spindle deep groove construction, a Conrad-type raceway with no built-in contact angle.
CR — phenolic outer land riding cage.
Precision Class: ABEC 3 / P6. Tighter bore, outside diameter and running-accuracy tolerances than a commercial-grade 6210, which is what puts this bearing on a machine-tool spindle rather than a general drive shaft.
Cage Material: Phenolic. Cage Type: CR – Phenolic outer land riding cage. A fabric-base phenolic cage guided on the outer ring land is much lighter than pressed steel, runs quieter at speed, and carries oil in the pockets.
Closure Type: Open. Lubricant: grease or oil. An open bearing takes whichever the spindle lubrication system supplies.
Bore Type: Straight. The bearing mounts directly on a ground journal with an interference fit.
Unit Quantity: 1 Pc. Single bearing, supplied loose.
The cross-referenced parts share the 50 x 90 x 20 mm ISO 6210 envelope at P6 tolerance with a fabric-base phenolic cage. The list is deliberately short: only executions confirmed at both P6 and a phenolic cage are given as interchanges, and a standard-cage 6210 is listed as a related size because the cage change alters the speed ceiling.
