Notes
- Teflon® liner permanently bonded to body id.
- Oscillation load shall be kept within the static load range, as Teflon® liner load endurance is greater than breaking load. For those under impact load or vibrational load, damage might occur even if the load is under the listed value.
- Made to order. (from RBT15 to RBT30)
- No load breakaway torque:
Standard type: All size:0.02~0.34N・m
Low torque type: All size:0.02N・m Max
(Radial play 0.05mm Max)

Feature of a Product
- Suitable for low load application.
- Self-lubricating.
Consist of a ball and a body. The body is directly swaged on the ball. For this reason, body material is usually high cold-working performance steel (303 stainless steel), and therefore have lower load carrying capacity compared to 3 piece / 4 piece Rod End Bearings. However, their economic cost and simple production makes them suitable for commercial applications with spacious construction. They do not require any lubrication, and in addition, stainless materials (303 for bodies, 440c for balls) enable the anti corrosion characteristics.
