Product Description

What this part is

Fafnir 2MM215WICR, a single super-precision angular contact ball bearing. Bore Diameter: 75 mm. Outside Diameter: 130 mm. Overall Width: 25 mm. Contact Angle: 15°. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Cage Material: Phenolic. Precision Class: ABEC 7/9 / P4S. Series: 200WI. Base Number: 2MM215WI. GTIN: 087796070882.

Decoding the designation

2MM — Fafnir super-precision spindle range at a 15° contact angle, ground to ABEC 7/9 (P4S) tolerances.

215 — 200 medium dimension series, bore code 15, which maps to the ISO 7215 envelope: 75 mm bore, 130 mm outside diameter, 25 mm width.

WI — low shoulder on both rings.

CR — phenolic cage.

What these specs mean in practice

Dynamic Load Rating: 87,900 N. Static Load Rating: 64,900 N. Limiting Speed: 10,800 rpm grease; 21,600 rpm oil. Item Weight: 1.174 kg (2.59 lb). The 200 medium series puts a larger ball complement in the same bore than the 9100 light series does, which is where the high dynamic rating comes from. A 15° contact angle favours speed and radial rigidity over thrust capacity.

Mounting data

Shaft Backing Shoulder Diameter: 85.2 mm. Housing Backing Shoulder Diameter: 120.8 mm. Maximum Housing Fillet Radius: 1.5 mm (0.059 in) — the largest housing corner radius the bearing corners will clear.

Quantity and configuration

Unit Quantity: 1 Pc. One single-row bearing. Fafnir grinds this execution universally, so two or more can be stacked back-to-back, face-to-face or in tandem and will reach the factory preload when clamped.

Interchange guidance
