Everything in the name of Sealing...
Series 25M
Series 25M are single coil spring elastomer bellow seals, being designed for general sealing purpose including easy installation of the seal. These seals have a unique rubber bellow secondary seal with self-aligning features which compensates abnormal shaft end play and run-out to provide service life. Shaft / sleeve fretting is avoided due to elastomeric bellow, the seal faces are driven through coil spring  and spring holder.

Series 25R
Series 25R are single coil spring seals with elastomeric bellow used for general, non-critical and light applications like water, oil, etc. These seals are not effected with the direction of rotation, as the acting torque is not transmitted through the coil spring. Single coil spring are provided for non-clogging, self-cleaning operation, and elastomeric bellow for self-alignment in case of radial and axial play in shaft, notches provided on seal faces and retainer gives extra positive drive.
