This new series of "Heavy Duty" pins   and rings has been designed by Caterpillar to guarantee a better pin-ring seal and to avoid the loss of the tooth.This new Cat series of pins and rings provides a much better pin-ring seal in all types of uses and especially in the most difficult situations.
Furthermore, the spiral- shaped ring construction guarantees the absorption of side loads, preventing the pin from sliding off.

This new series is perfectly interchangeable with the series currently on the market.
Example:
PIN    : 114-0358 = 8E6358 = 9J2358
RING   : 114-0359 = 8E6359 = 3G9549
