Polaris RZR Wheel Bearing Rocky Mountain ABEC5 Chrome Steel 44720033

Description

Product Overview

The Rocky Mountain Bearings Polaris RZR Wheel Bearing is engineered for the most demanding off‑road enthusiasts. Constructed from high‑carbon steel, the inner race offers exceptional strength while the nitrile rubber seals protect against dust, mud, and water ingress. The bearing meets ABEC‑5 standards, delivering precise tolerance and smooth rotation for a wide range of Polaris models.

Measuring 72 mm in outside diameter and 33 mm in thickness, this ball bearing fits directly into the wheel hub assembly without modification. The chrome‑steel exterior provides a corrosion‑resistant surface that maintains its luster even after prolonged exposure to harsh environments. With a load rating that exceeds OEM specifications, the bearing supports the heavy torque demands of RZR Turbo, RZR XP Pro, and Scrambler variants.

Compatibility is a core strength of this product. It replaces OEM part numbers 3514627, 3514699, 3514822, 3514924, and 3515090, making it a universal solution for Polaris RZR 900 (2011‑2025), RZR 1000 (2014‑2025), Scrambler 850 (2013‑2025), Scrambler 1000 (2014‑2025), and General 1000 models through 2025. The bearing’s design also accommodates the RZR RS1 (2018‑2022) and turbo‑charged variants up to 2021, ensuring a single part can service multiple vehicle generations.

Usage

Designed for both recreational riders and professional racers, this bearing thrives in environments where reliability is non‑negotiable. Whether you are tackling rocky trails, sand dunes, or muddy forest paths, the sealed design prevents contaminants from compromising performance. The high‑carbon steel core endures the repeated shock loads generated by rapid acceleration and sudden braking, delivering consistent handling and stability.

Installation is straightforward for experienced mechanics and DIY owners alike. The bearing slides into the hub housing, and the included grease‑compatible seal ensures optimal lubrication without the need for additional greasing steps. After installation, riders notice an immediate reduction in wheel wobble and noise, translating to smoother rides and extended component life.

Beyond the typical trail use, the bearing is suitable for competitive events such as enduro races and hill climbs where every millisecond counts. Its ABEC‑5 precision reduces rotational friction, allowing the drivetrain to transfer power more efficiently. This efficiency can translate into measurable gains on the track, especially when paired with high‑performance tires and suspension upgrades.
