“J” Type: Two piece ribbon consisting of two halves that are assembled one half from one side, and the other half from the opposite side. Fold down tabs secure the two halves. This type of cage is guided by the balls. “Loose” clinch type provides lower torque. Material is type 302 stainless steel. Brass and carbon steel are also available. These types of cages can operate at low to moderately high speeds. Loose crimp is standard. Tight crimp (JF) is used for higher speeds. Extra loose (JL) is used for low torque applications.
“W” Type: One piece steel crown. Mainly used in very small bearings. This type of cage is inner ring guided. Material is type 410 stainless steel. The cage snaps in from one side over the balls. It has excellent performance in low torque, low speed applications. Generally, the one piece steel crown is not used in high speed applications.
“RJ” Type: This type of cage is suitable for larger bearings (bore diameters over 10mm) with high load carrying capacities. It is a two piece ribbon consisting of two halves that are assembled one half from one side, and the other half from the opposite side. The two pieces are riveted together and are strong enough to with stand higher levels of vibration and acceleration. This type of cage is guided by the balls. Material is type 302 stainless steel or carbon steel sheet.
"TW” Type: Molded nylon cage. Reduces fluctuations in running torque and is suitable for high speeds. This type of cage is guided by the balls. The operating temperature range is from -30º C to +120º C. Also, available with a glass fiber reinforced nylon that is more rigid and capable of higher speeds.
“THB” or “THA” Type: Phenolic resin machined one-piece snap in crown type. These retainers have high rigidity and emergency running characteristics. Can be vacuum impregnated with oil. These are used in high speed deep groove ball bearings. “A” designation is for outer ring guided, and “B” designation is for inner ring guided. The operating temperature range is from -50º C to +140º C.
“TxHB” or “TxHA” Type: Machined one-piece snap in crown type made from special materials. These retainers have high rigidity and emergency running characteristics. These are used in high speed deep groove ball bearings. “A” designation is for outer ring guided, and “B” designation is for inner ring guided. The operating temperature range is from -50º C to +260º C depending on the material. “x” is a number code for the special material.
“TA” or “TB” Type: One piece full machined type made of phenolic resin material. These retainers have high rigidity and emergency running characteristics. Can be vacuum impregnated with oil. These are used in angular contact bearings only. “A” designation is for outer ring guided, and “B” designation is for inner ring guided. The operating temperature range is from -50º C to +140º C.
“TxA” or “TxB” Type: One piece full machined type made from special materials. These retainers have high rigidity and emergency running characteristics. These are used in AC type bearings only. “A” designation is for outer ring guided, and “B” designation is for inner ring guided. The operating temperature range is from -50º C to +260º C depending on the material. “x” is a number code for the special material.
