The Best Snow Blower Bearings

Snow blower bearings are small but critical components that keep your auger and impeller spinning smoothly. When a bearing fails, the blower vibrates, makes noise, or stops throwing snow entirely.

Choosing the right replacement, whether a ball bearing or flange type, requires knowing your machine’s make, model, and shaft size.

This guide compiles expert review consensus and verified buyer feedback to help you identify the best snow blower bearings for your specific equipment.

We evaluated dozens of bearings from leading brands using consistent criteria: material quality, dimensional accuracy, brand compatibility, and value. Each product received an SRW Score based on its performance in these categories.

Below you’ll find our top picks, followed by a detailed buying guide to help you make the right choice for your snow blower.

Best Snow Blower Bearings Buying Guide

Bearing Type: Ball vs. Flange

Snow blower bearings come in two main types: ball bearings and flange bearings. Ball bearings are round and often used in the auger housing, while flange bearings have a square mounting plate for bolting onto shafts or brackets.

Check your original part to determine which style you need. Many replacement kits include both types, but using the wrong style can lead to improper fit and premature wear.

Flange bearings are common on Troy-Bilt, MTD, and Craftsman models, while ball bearings are found on Husqvarna, Toro, and Ariens machines.

If you’re unsure, consult the manufacturer’s parts diagram or refer to a trusted Troy Bilt snow blower guide to identify the correct bearing type.

Shaft Size and Inner Diameter

The inner diameter (ID) of the bearing must match the shaft it rides on. Common IDs include 3/4-inch, 1-inch, and 5/8-inch. Measure the shaft diameter with calipers or refer to the original part number.

Using a bearing with the wrong ID will cause slippage or binding. Most aftermarket bearings list compatible shaft sizes in the product description.

For example, the replacement bearing assembly for Toro Powermax models uses a 12-8789 part that fits specific shaft diameters. Cross-referencing with original parts like 26-6100 ensures a snug fit.

Material and Seals

Bearings are typically made of chrome steel or stainless steel. Chrome steel offers high load capacity and durability, while stainless steel resists corrosion, an advantage in salty, wet snow conditions.

Sealed bearings (2RS) have rubber shields that keep out debris and retain grease, extending bearing life. Avoid open (metal-shielded) bearings for snow blowers as they allow moisture ingress.

Check if the bearing uses a metal or rubber seal. Rubber-sealed bearings are preferred for snow blowers because they block moisture and fine snow particles. Many top-rated bearings in our list, such as those from Husqvarna and MTD, come with dual rubber seals.

Brand Compatibility and OEM vs. Aftermarket

OEM bearings (e.g., genuine Husqvarna, Cub Cadet, or MTD) guarantee exact fit and material quality, but they cost more. Aftermarket bearings from reputable brands often match OEM specifications at a lower price.

Verified buyer feedback suggests that aftermarket bearings from SureFit, DEEG, and other vendors perform well when they list direct OEM cross-references.

If you’re replacing a bearing on a Husqvarna ST series, the SureFit ball bearing replacement (ASIN B07G5WLBVX) is a popular choice. For MTD-based machines (Craftsman, Yard-Machines), the flange bearing B0017OX366 often serves as a direct replacement.

Review the compatibility list carefully, and if needed, consult large driveway snow blower options for heavy-duty machines.

Price vs. Value Considerations

Bearings range from budget-friendly multi-packs to higher-priced OEM units. While price is a factor, consider the total cost of ownership: a cheap bearing that fails mid-season requires replacement labor and downtime.

The highest SRW Score bearings in our list, like the 12-8789 assembly and the MTD 741-0309, offer a good balance of durability and cost.

For those on a tight budget, multi-packs such as the 2-pack of 941-0300 flange bearings provide good value without sacrificing quality. Ensure the bearing’s load rating matches your machine’s weight and speed requirements.

If you frequently clear heavy, wet snow, investing in a premium bearing can prevent early wear.

Frequently Asked Questions

How do I know which bearing size my snow blower needs?

Check the shaft diameter using a caliper, or look up your machine’s model number in the owner’s manual. Many bearings list the inner diameter and compatible OEM part numbers.

If you still can’t identify the size, a local small-engine repair shop can help.

Can I replace a ball bearing with a flange bearing?

Only if the mounting system is designed for it. Flange bearings bolt onto brackets, while ball bearings press into housings. Attempting to substitute one for the other may lead to poor fit and failure. Always replace with the same type as the original.

Are aftermarket bearings as good as OEM?

Many aftermarket bearings match OEM specifications in material and dimensions. Verified buyer feedback on top-rated aftermarket brands shows they often perform well. However, for critical applications or very high-use machines, OEM parts provide guaranteed compatibility.

How often should I replace snow blower bearings?

There is no set interval; bearings should be replaced when they show signs of wear like noise, vibration, or rough rotation. Inspect them at the start of each season, especially if your machine is several years old. Regular greasing can extend their lifespan.

What’s the difference between a ball bearing and a flange bearing?

A ball bearing is a round unit that sits inside a housing, while a flange bearing has a flat mounting plate with bolt holes. Flange bearings are easier to replace if the machine’s bracket is accessible.

Ball bearings are more common in auger shafts and impeller assemblies.
