SKF 6209 JEM

Description

Deep Groove Ball Bearings or Radial Ball Bearings are particularly versatile. They are suitable for high and very high speeds, accommodate radial and axial loads in both directions, and require little maintenance. These characteristics coupled with a price advantage make deep groove ball bearings the most popular of all rolling bearings. Because they are the most widely used bearing type, they are available in many designs, variants, and sizes. The most commonly used type is the single row bearings without filling slots (Conrad assembly).

Design Variants:

• Open Basic
• Shields (designation suffix Z)
• Non-contact Seals (designation suffix RZ)
• Low-friction Seals (designation suffixes RSL or RST)
• Contact Seals (designation suffixes RSH, RSH2, RS1 or RS2)
• Snap Ring/Snap Ring Groove (designation suffixes N, NR, ZNR, ZNBR, 2ZNR)

Applications

Deep groove ball bearings are used in applications that require quiet operation, smoothness, strength, and low heat generation. They are capable of meeting the most severe demands in terms of operating speed, operating temperature, vibration, high running accuracy, low friction, and the ability to function in contaminated environments with seals and shields.

Features/Advantages

• Available in a wide range of sizes (2.5 to 800mm inside diameter) with a choice of shields, seals, and snap rings.
• In the USA, SKF offers bearings with C3 internal clearance, steel cages, and quiet running characteristics packaged as JEM bearings. The box will be marked JEM while the bearing is marked C3 and/or GJN pending if the bearing is open or capped.
• SKF provides GJN, a high temperature urea based grease, as the standard for all JEM deep groove ball bearings. GJN is accepted by major OEM electric motor manufactures in the U.S.
