NSK22216L11CAME4C3Spherical Roller Bearing – Straight Bore, 80 mm ID, 140 mm OD, 33 mm Width, Open, C3 Internal clearance.

Product Description

What this part is

NSK 22216L11CAME4C3 double-row spherical roller bearing. Bore: 80 mm. Outside diameter: 140 mm. Width: 33 mm. Series: 22200. Bore form: straight cylindrical. Two rows of barrel-shaped rollers run on a common spherical outer raceway, so the bearing carries heavy radial load together with axial load in both directions and accommodates shaft deflection and housing misalignment up to 2°.

Decoding the designation

L11: rings dimensionally stabilised for elevated-temperature service. CA: machined cage design. M: brass cage material. E4: a lubrication groove in the outer ring with three radial feed holes, equivalent to the W33 feature. C3: internal radial clearance greater than normal. Cage Type: Machined. Cage Material: Brass. Internal Clearance: C3. Precision Class: ABEC 1 / P0. Country of origin on this item: Japan.

Published ratings

Dynamic Load Rating: 225 kN (50,582 lbf). Static Load Rating: 271 kN (60,923 lbf). Limiting Speed: 4,800 rpm. Operating temperature range: −30 °C to 200 °C. Maximum permissible misalignment: 2°. Item weight: 4.30 lb. On a double-row spherical roller bearing the static rating standing above the dynamic rating is the normal published relationship for the type.

What these specs mean in practice

A machined brass cage carries higher roller loads and higher speed than a pressed cage, and tolerates the 200 °C ceiling the L11 stabilisation supports. C3 clearance leaves running clearance after the interference fit and after thermal growth of the inner ring, which suits shafts that run warm. The E4 groove feeds lubricant straight to both roller rows through the outer ring, so the bearing is relubricated in service without dismounting.

Fitting notes

The bore is straight, so the bearing presses directly onto a cylindrical shaft seat with no adapter sleeve in the mounting. The outer ring is drilled for the E4 feed holes, so the housing bore needs a matching lubrication port for the groove to be used.

Quantity and configuration

One bearing, open on both faces. Unit Quantity: 1 Pc.

Interchange guidance

Same-envelope straight-bore equivalents include SKF 22216 E/C3 and FAG 22216-E1-C3. The tapered-bore forms — 22216 K, 22216 EK, 22216KCJW33C3 — are a related size on the same envelope with a 1:12 bore, and they mount on an adapter sleeve rather than directly on the shaft.
