203KRR5-C3 PFI Agricultural Deep Groove Ball Bearing C3 Clearance (ID 13.08mm OD 40mm W 18.29mm)

The PFI 200KRR is a shielded deep groove ball bearing designed for robust operation in agricultural machinery. It provides dependable radial and axial load support, offering long service life under moderate operating speeds. Manufactured to high dimensional accuracy and durability standards, this bearing is suited to demanding field conditions where consistent performance is essential.

Product Overview

The PFI 200KRR bearing belongs to the agricultural series commonly used in applications such as disc harrows, seeders, and conveying equipment. It integrates high-quality steel components with precision grinding to maintain reliability even in harsh environments. Its internal geometry minimises friction and heat generation while ensuring smooth motion during operation.

Design Features

This bearing incorporates a deep groove raceway profile, which allows it to accommodate combined loads effectively. It is sealed on both sides to protect the rolling elements from dust, grit, and moisture, enhancing its suitability for agricultural service. The inner ring features an extended and narrow-width design, providing a stable fit when mounted within housings or flanged units. The bearing is pre-lubricated with high-quality grease for initial service, reducing maintenance requirements on installation.

Functional Characteristics

The PFI 200KRR bearing exhibits steady load distribution and uniform contact between the balls and raceways, contributing to reduced wear over prolonged use. Its robust sealing prevents contaminant ingress, maintaining lubricant integrity during cyclic loading and vibration exposure typical of field machinery. The heat-treated bearing steel construction ensures dimensional stability across temperature variations and heavy duty cycles.

Use in Assemblies

In agricultural equipment, the PFI 200KRR is often used as a replacement bearing in flanged or pressed steel housings. It facilitates axial positioning on shafts through its extended inner ring, allowing for straightforward alignment during assembly. Commonly found in tillage implements and harvesting systems, it supports rotating shafts transmitting both radial and limited thrust loads in dynamic environments.
