Toyota Corolla And Toyota Levin/Leiling gearboxes B76-2AaNX4 76x110x15mm

Product Overview

The B76-2ANX4(correct designation; the listing’s “B76-2AaNX4” appears to be a typographical variant)is a single-row deep groove ball bearing with a 76 mm bore × 110 mm outside diameter × 15 mm width, catalogued by NSK as an automotive deep groove ball bearing for gearbox applications. It is produced from GCr15 chrome steel and is supplied open(no integral seals)for lubrication by the transmission oil circuit.

Critical corrections before publication

1. Model designation: “B76-2AaNX4” should be “B76-2ANX4”

The supplier form lists the model as B76-2AaNX4. Every accessible catalogue entry — NSK, RICH, and aftermarket distributors across Thai, Polish, German, Vietnamese, Dutch, and Spanish listings — uses the designation B76-2ANX4 with a capital “A” and no lower-case “a” between the “2” and “N”. The “Aa” in the supplier form is almost certainly a typo. Publishing an incorrect model number will hurt search visibility and may cause buyers referencing the correct NSK designation to miss the listing entirely.

2. Cage material: catalogue data consistently shows nylon, not steel

The supplier form specifies Steel Cage / Steel. However, the NSK catalogue listings and aftermarket product pages consistently describe the B76-2ANX4 as equipped with a nylon cage(ไนลอน Cage / Klatka nylonowa / Nylonkäfig / chuồng nylon). The Keyword 3 in the supplier form also references “nylon cage ball bearings,” which contradicts the “Steel Cage” entry in the structural fields. The cage fields should be corrected to Nylon unless the supplier has physical stock evidence that this particular batch is steel-caged.

3. Weight: 0.4 kg is consistently published

The supplier form leaves the Weight field blank. Multiple independent catalogue entries report 0.4 kg for the B76-2ANX4. This should be populated in the listing.

Load ratings and speed limits: not published

No accessible public catalogue publishes Cr, C0r, grease speed, or oil speed for the B76-2ANX4 in its NSK automotive designation. The available sources provide dimensions, weight, cage type, precision grades, and seal type, but not standard ISO load ratings. These fields should remain blank or be marked “Consult supplier” rather than estimated from a generic 76 × 110 × 15 mm deep groove ball bearing. This is consistent with the pattern across the preceding vehicle-specific listings: OEM gearbox bearings are specified by fitment and assembly position, not by published catalogue load ratings.

Key Specifications

Performance Features

• Gearbox-specific envelope: The 76 mm bore × 110 mm OD × 15 mm width is sized to a specific gearbox shaft position where a standard metric bearing would not provide the correct shoulder dimensions or axial spacing.

• Deep groove geometry for combined loads: The single-row deep groove raceways carry radial loads and accommodate moderate axial loads in both directions, matching the combined load spectrum of a transmission shaft under gear mesh forces.

• GCr15 chrome steel construction: Rings and balls are through-hardened for rolling-contact fatigue resistance under the cyclic loading of automotive gearbox service.

• Nylon cage: The nylon cage provides low-friction ball guidance and is suited to the oil-lubricated environment of a gearbox. The catalogue-confirmed nylon construction is consistent with the supplier’s own Keyword 3 reference to “nylon cage ball bearings.”

• Open configuration for oil lubrication: No integral seals, the bearing is lubricated by the gearbox oil circuit, consistent with the wet-sump lubrication strategy of a manual or automatic transmission.

Application

The B76-2ANX4 is catalogued as an automotive deep groove ball bearing for gearbox applications. The supplier form specifies fitment for Toyota Corolla and Toyota Levin/Leiling gearboxes. In service, a bearing of this type supports a gear shaft under the radial and moderate axial loads generated by the gear train. The 76 × 110 × 15 mm envelope and the open, oil-lubricated configuration are consistent with a direct-fit gearbox service bearing. Replacement requires transmission disassembly and should follow the vehicle manufacturer’s procedure for bearing installation and shaft end-play adjustment.
