M MATI Wheel Bearings 44x72x33 Front & Rear for Polaris RZR, Sportsman — Stainless-Seal, Heavy-Duty Set (4)

M MATI Wheel Bearings 44x72x33 are direct-fit front and rear replacements engineered for Polaris RZR, General, Sportsman and Scrambler models to restore smooth wheel rotation and reliable service life.

These bearings are an OEM-compatible repair option designed to match factory fit and function across a wide range of Polaris ATV and UTVs. Built with thicker steel components, stainless-steel seal covers and G10Z4 steel balls, the set provides a durable alternative to standard rubber-sealed units. Each kit includes four 44x72x33 bearings and four retaining rings, shipped in a protective box and tested for vibration and quality before packaging.

Which Polaris models use these 44x72x33 bearings?

The M MATI bearings fit many Polaris machines from mid-2009 through 2022. Compatibility covers high-volume wheel and hub applications on RZR, Sportsman, General and Scrambler families so you can use the same part for both front and rear where specified.

• RZR 1000 (2014–2022), RZR 900 (2011–2022)
• RZR PRO XP (2020–2022), RZR RS1 (2018–2022), RZR Turbo (2016–2021)
• Sportsman 1000 (2015–2022), Sportsman 550 (2009–2014), Sportsman 850 (2009–2022)
• General 1000 (2016–2022), Scrambler 1000 (2014–2022), Scrambler 850 (2013–2022)

How do these bearings differ from stock or economy replacements?

M MATI upgraded bearings use a stainless-steel cover as the sealing element instead of a basic rubber seal. The thicker steel construction and G10Z4-grade steel balls increase resistance to impact and wear while factory-style testing reduces the risk of premature failure.

• Stainless-steel seal covers for improved debris resistance
• Thicker steel housing for enhanced durability under load
• G10Z4 steel balls for consistent rolling performance
• Vibration and quality tests to ensure factory-fit replacement

What comes in the package and how easy is installation?

The kit contains four 44x72x33 bearings plus four retaining rings, all packed in a protective box for shipping. Installation follows the same steps as the original bearings, so any mechanic familiar with Polaris hubs can replace them with standard tools and basic mechanical experience.

• 4 x bearings (44x72x33) and 4 x retaining rings included
• Boxed for safe storage and transport
• Direct-fit dimensions match OEM part numbers (see fitment list)
• Standard hub press or bearing driver recommended for installation

What warranty and support are offered if something goes wrong?

M MATI provides a one-year product service window for issues reported after purchase. Contact the seller within that period for assistance, replacement, or troubleshooting — the company commits to helping resolve legitimate product defects.

• 1-year support service for product problems
• Customer contact for replacement or resolution
• Items tested prior to shipment to reduce defects

Who is this for? The M MATI 44x72x33 bearing kit is aimed at Polaris owners, professional mechanics and shop technicians who need a rugged, cost-effective replacement for worn or damaged wheel bearings. It’s suited for off-road riders who demand stronger seals and thicker steel than basic economy parts, and for fleet maintainers seeking consistent, tested components that match common OEM part numbers.
