PK Series Track Rollers are heavy-duty roller bearings widely used in linear motion systems, originally standardized by NADELLA. They adopt a double-row roller structure with strong radial load capacity, impact resistance and anti-overturning performance. Available in concentric (PK) and eccentric (PKR) versions, these track rollers are equipped with keyways, seals and high-hardness bearing steel construction, suitable for heavy machinery, automated production lines, CNC equipment and logistics conveying systems. They feature stable operation, reliable sealing and long service life under harsh industrial conditions.
