FAQ

What Yamaha models are compatible with this bearing?

The bearing fits Yamaha ATV and UTV models that use the OEM part numbers 99009‑55500‑00 or 93305‑00602‑00. Specifically, it is compatible with the Big Bear 400 IRS (2007‑2012), Grizzly 350 IRS (2007‑2011), Grizzly 400 (2007‑2008), Grizzly 450 (2007‑2014), and other Yamaha UTVs that share the same rear wheel dimensions. Always confirm the vehicle’s year and IRS configuration before purchase to ensure a proper fit.

How do I install the bearing correctly?

Begin by safely lifting the ATV or UTV and removing the rear wheel. Extract the old bearing using a bearing puller or appropriate tool, taking care not to damage the hub. Clean the hub surface, then align the new JAVIK bearing with the mounting holes. Press the bearing into place using a hydraulic press or a bearing installer tool, ensuring even force. Finally, install the circlips on both sides to lock the bearing, re‑mount the wheel, and torque the axle nut to the manufacturer’s specification.

What maintenance is required after installation?

After installing the bearing, monitor the rear wheel for any unusual noises or vibrations during the first 50 miles of operation. Re‑apply grease if you notice increased friction, and check the circlips periodically to ensure they remain securely seated. Perform a visual inspection of the bearing housing every 200 miles, looking for signs of wear, corrosion, or grease leakage. Replace the bearing if any damage is detected, and always follow the manufacturer’s recommended torque settings for the axle nut.

Can I use this bearing on non‑Yamaha vehicles?

The bearing is engineered to match the OEM specifications for Yamaha ATV and UTV rear wheels, but its dimensions—55 mm outer diameter, 30 mm inner bore, and 32 mm width—are common among many off‑road and utility vehicles from other manufacturers. If the target hub has the same bore size and mounting configuration, the bearing can be installed as a direct replacement. However, we recommend verifying the hub’s bearing housing dimensions and consulting the vehicle’s service manual before fitting the part on a different brand. In cases where the hub differs, adapters or custom machining may be required, which could affect performance and warranty coverage.

What is the recommended lubrication schedule?

For optimal performance, we advise applying a high‑temperature lithium or silicone‑based grease to the bearing during installation. After the initial break‑in period of approximately 50 operating hours, inspect the bearing every 200–300 hours of use, especially if the vehicle is subjected to heavy loads or harsh conditions. Re‑apply grease if you notice any increase in noise, vibration, or temperature rise. In environments with excessive dust or water exposure, more frequent checks—every 100 hours—can help prevent contamination and extend the bearing’s service life. Always use a grease that meets the NLGI grade 2 specification to ensure proper flow and protection.
