695-2RS Bearing (5x13x4)

Description

The 695-2RS bearing is a 5 x 13 x 4 mm miniature ball bearing with rubber seals on both sides. It’s made from AISI 52100 bearing steel, also known as GCR15 or 100Cr6, and heat hardened to Rc 59–64 before final grinding and polishing. The result is a tough, smooth-running bearing with excellent wear resistance and a long service life, built for small assemblies that need dependable performance.

Why Choose a Rubber Sealed Bearing?

The “2RS” in 695-2RS means the bearing has a rubber seal on each side. Rubber seals make contact with the inner ring, creating a tight barrier against water, mud, fine dust, and grit. That makes a sealed bearing the better choice for anything that runs outdoors, gets wet, or works in dirty conditions. The seals also hold the factory grease in, so the bearing stays lubricated for a long time without any maintenance. The trade-off is slightly more drag than a shielded bearing, which matters little in most applications.

Built From Proven AISI 52100 Bearing Steel

AISI 52100 is a high-carbon chrome steel and one of the most widely used bearing materials in the world. Heat hardening it to Rc 59–64 gives the balls and raceways a hard, durable surface that resists wear under repeated loading. Final grinding and polishing then give the bearing a smooth finish, so your 695-2RS bearing runs quietly with low friction.

Where Is the 695-2RS Bearing Used?

Its small size and sealed design make this bearing a popular choice for:

• RC cars, trucks, and other hobby models
• Small electric motors and fans
• 3D printers and small CNC machines
• Pulleys, rollers, and idlers
• Tools, instruments, and light-duty machinery

Installation and Care Tips

Always press the bearing in squarely and evenly. Push on the outer ring when fitting it into a housing and on the inner ring when fitting it onto a shaft, so no force passes through the balls. Take care not to puncture or dent the rubber seals during installation. Because 52100 steel isn’t stainless, dry the bearing off after wet use where possible, and store spares somewhere dry. Replace the bearing if you notice roughness, noise, or play.

695-2RS Bearing FAQ

What’s the difference between 695-2RS and 695ZZ?
They’re the same size. The 2RS version uses rubber seals for better protection against water and dirt, while the ZZ version uses metal shields, which create a little less friction.

Do I need to grease a sealed bearing?
No. It comes pre-lubricated, and the seals keep the grease in, so it’s ready to install straight out of the package.
