Cages/Retainers

Designs and materials used for the retainers are suited to the task. Our two-piece ribbon retainer is sufficient in the majority of cases.

The following table shows the different types:

Retainer Code	Picture	Description / Material	Application Range / Purpose
E J Y		Two-piece ribbon retainer made of — Steel sheet (E) — Stainless steel sheet (J) — Brass sheet (Y)	For deep groove ball bearings. For stainless steel ball bearings: retainer from stainless steel sheet. This retainer can also be clinched loosely to reduce torque.
JH		One-piece stainless steel snap type retainer.	For deep groove ball bearings. Mainly used for small ball bearings at low and medium speeds.
TNH		One-piece molded synthetic snap type retainer.	For deep groove ball bearings. Good running and torque characteristics for medium speed range. Working temperature -30 °C to 80 °C (short term 100 °C).
TN9H		One-piece glass-fibre reinforced molded synthetic snap type retainer.	For deep groove ball bearings. Speed range higher than TNH retainer. Working temperature -30 °C to 120 °C (short term 180 °C).
THA THB		Machined one-piece snap type retainer made from reinforced phenolic resin. A = outer ring guided. B = inner ring guided.	For high-speed deep groove ball bearings. High rigidity and emergency running characteristics. Working temperature -50 °C to 140 °C. Can be vacuum impregnated with oil.
TXHA TXHB		Machined one-piece snap type retainer made from special materials. X stands for a number indicating the material. A = outer ring guided. B = inner ring guided.	For high-speed deep groove ball bearings. High rigidity and emergency running characteristics. Working temperature -50 °C to 260 °C depending on material.
TA TB		Machined one-piece, solid retainer made from fabric reinforced phenolic resin. A = outer ring guided. B inner ring guided. Only for AC types.	For high-speed angular contact! spindle ball bearings. High rigidity and emergency running characteristics. Working temperature -50 °C to 140 °C. Can be vacuum impregnated.
TXA TXB		Machined one-piece, solid retainer made from special material. X stands for a number indicating the material. A = outer ring guided. B = inner ring guided. Only for AC types.	For high speed angular!spindle ball bearings. High rigidity and emergency running characteristics. Working temperature -50 °C to 260 °C.
VAC1 VAC2		Full complement ball bearing, without retainer, cannot be disassembled. VAC1 = one shoulder relieved on outer ring. VAC2 = one shoulder relieved on inner ring.	Used for medium speeds and high axial loads in one direction only.
