Lubrication
There is no known universal grease for all bearing applications; it is therefore required to have a complete understanding of the operational environment. Because conditions of service are often difficult to properly analyze, we recommend you consult our engineering department for recommendations. There are many fine selections available, here are only a few:
Lubrication	Temperature	Base Oil	Thickener	MIL-Spec
	Range (F)
Alvania #2	-30 to +230	Petroleum	Lithium Hydroxy	MIL-G-18709A
Beacon 325	-60 to +250	Synthetic	Lithium Hydroxy	MIL-G-3278A
Chevron SRI #2	-20 to +350	Petroleum	Polyurea	MIL-G-3545C
Kyudo Yushi SRL	-40 to +300	Synthetic	Lithium Hydroxy
Mobil Grease 28	-80 to +350	Synthetic	Synthetic	MIL-G-8132

Retainers (Cages)
Cages are used to perform an important function, the separation of the rolling elements within the bearing races. It is important for a smooth and efficient operation that the rolling element be guided in and out of the load zone. Retainers come in several configurations and material types that include:
Pressed Steel Finger
Pressed Steel Riveted
Molded Nylon

Shields
Especially configured low carbon non-removable steel plates (Z) are staked into the outer ring of the bearing to provide protection against coarse dirt or chips from contaminating the bearing. Shields are especially useful in high temperature applications and where low torque is required. Stainless Steel is available upon request.
Seals
Radial bearings fitted with rubber seals (RS) in the outer ring, provide a wiping action to provide an effective barrier against contamination. Seals contain a carbon steel plate to assist in keeping the seal from being pushed inward by external forces. Seals with light wiping action provide lower torque and are often called non-contact seals. Materials selected for use often depend on the operating temperature of the application. Materials include:
Buna N
Polyacrylic

Electric Motor Quality
For a quiet and smooth operation, JUF supplies electronically tested Electric Motor Quality (EMQ). Bearings are 100% tested for noise and vibration.
Tolerances
JUF Bearings manufactures bearings to ABEC 1 dimensional tolerances. ABEC 3, 5 are also available.
Internal Radial Clearances
Our standard product line is normally produced with "C0" radial clearance. Other radial clearances are available.
