An Inner race and roller bearing are used in transmission applications to facilitate smooth and reliable rotational motion. It contains an inner race, a set of rollers, and an outer race. The inner race is a ring-shaped component designed to fit onto a shaft or spindle. It provides a mounting surface for the rollers and helps transmit the rotational force from the shaft to the bearing assembly.

Attributes:
• Withstands harsh operating conditions and provide long-lasting performance.
• Enables smooth and reliable rotational motion with minimal friction.

Applications:
An Inner race and roller bearing help in ensuring the efficient and reliable performance of machinery and equipment.
