FAQ

What is a solid oil / solid lube bearing?

It's a standard deep groove ball bearing whose internal free space is filled with a polymer matrix saturated with lubricating oil. The polymer holds the oil in place and releases a thin film onto the balls and raceways as the bearing turns. Visually it resembles a rubber-sealed bearing — the fill takes the place of seals — but it never needs regreasing and nothing can wash out.

Which option do I need: Standard or Food Grade?

Standard bearings use chrome steel rings with our standard solid lubricant — the right choice for general industrial use. Food Grade bearings use stainless steel rings with NSF H1 registered food grade solid lubricant — required for food and beverage processing and recommended for washdown and corrosive environments.

What do the SKUs mean?

Example for a 6203 size: 6203-SL is the standard chrome steel bearing with solid lube. S6203-FGSL is the stainless steel version with food grade solid lube (S = stainless, FG = food grade, SL = solid lube).

How do I find the right size?

Use the Bearing Finder — enter any combination of bore (ID), outer diameter (OD), and width in mm or inches, and it will show every matching bearing we make.

How long does my order take?

All bearings are impregnated to order. Typical production time is added on top of normal shipping time — you'll receive tracking as soon as your order ships. If you have a deadline, contact us before ordering.

Can I return or cancel my order?

No — because every bearing is made to order, all sales are final and orders cannot be canceled once production begins. See our Return Policy. Damaged, defective, or incorrectly shipped items are always replaced.

Are there speed or temperature limits?

Solid lube bearings generally run at reduced maximum speed compared to grease lubrication (roughly 40–60% of the open-bearing rating) and are suitable for continuous temperatures up to approximately 90 °C. For high-speed or high-temperature applications, ask us and we'll confirm suitability.
