The wheel bearing greaser helps keep bearings lubricated during long-term operation. This bearing grease tool replenishes needed grease while helping to push out contaminants. Simple to use—insert it into the bearing and pump grease through the zerk fitting using a grease gun (not included). Fits Polaris UTV and ATV wheel bearings with a 44mm (1.7in) inner diameter. The inner bearing races are separated by seals, creating space for grease to flow easily inside, enhancing bearing performance. Made from high-quality aluminum with 2 O-rings for improved sealing to retain grease within the bearings.
