KEMIMOTO 44mm Wheel Bearing Greaser for UTVs — Aluminum O‑Ring Seal, Fits Polaris RZR & Ranger

The KEMIMOTO 44mm Front Rear Wheel Bearing Greaser is an aluminum, O-ring sealed tool designed to quickly and cleanly inject grease into 44mm wheel bearings on UTVs like Polaris RZR and Ranger.

Maintaining wheel bearings on off-road UTVs requires the right-size greaser that fits tight hubs, resists corrosion, and keeps lubricant where it belongs. This 44mm greaser from KEMIMOTO is machined from aluminum for a lightweight, corrosion-resistant body, uses an internal stepped bore to clear CV shafts, and employs an O-ring seal to reduce mess while pumping grease deep into front and rear wheel bearings.

What vehicles and wheel locations does this 44mm greaser work with?

This tool is built to service a broad range of Polaris and similar UTVs. It fits common 44mm bearing access points used on many RZR, Ranger, and other off-road utility models, allowing both front and rear wheel bearing greasing where applicable.

• Compatible with Polaris RZR 570/800/900/1000, XP Turbo, and XP 1000 models
• Fits Polaris Ranger 500/570/800/900/XP 1000 hubs
• Works on select models of Scrambler, Sportsman, General and similar UTVs with 44mm bearing access
• Designed to clear CV shafts for rear hub applications on models that share the 44mm bore

How does the tool keep grease from leaking and making a mess?

The KEMIMOTO greaser uses a durable O-ring seal where the tool meets the hub opening, reducing escaped grease during pumping. The internal design also slows back pressure so grease flows into the bearing cavity rather than spraying out the joint.

• O-ring seal retains grease at the tool-to-hub interface
• Internal stepped bore reduces back pressure and prevents blowback
• Precision fit minimizes side leakage for cleaner service jobs

What are the build details and durability features?

Machined from aluminum, the greaser offers a lightweight yet corrosion-resistant body suited for garage and trail-side use. The knurled exterior improves grip when installing and removing the tool, even with oily hands or gloves.

• Aluminum construction provides low weight and natural corrosion resistance
• Knurled surface for a secure, non-slip grip during installation
• Precision machining for consistent 44mm fitment and longevity

How do you use the KEMIMOTO 44mm greaser in a maintenance routine?

Using the greaser is straightforward: clean the hub access, seat the tool over the bearing opening until the O-ring seals, then pump grease through a standard grease gun. The internal step clears space for CV shafts, making it suitable for both front and certain rear applications without disassembly.

• Wipe hub access and inspect seals before attaching the tool
• Attach a standard grease gun to the tool and pump until clean grease appears from bearing vents
• Remove tool and wipe remaining residue; check bearings for free rotation

Who is this for: This greaser is aimed at UTV owners, mechanics, and fleet techs who perform regular bearing maintenance on Polaris RZR, Ranger, Scrambler, Sportsman, General and similar off-road vehicles. It suits users who want a durable, precise 44mm greasing solution that reduces mess and speeds service time, whether in a home garage or out on the trail.
