Double-Row Full-Complement Cylindrical Roller Bearings

Name: Double-Row Full-Complement Cylindrical Roller Bearings
Brand: WKB (Wafangdian) Bearing Technology Co., Ltd.
Price: 150-800 USD
Rating: 4.8 (50 reviews)

Double-row full-complement cylindrical roller bearings boast two rows of rollers without cages, increasing radial load capacity. They excel in heavy-duty applications, providing enhanced radial and moderate axial load capabilities. While alignment tolerance and durability are advantages, managing heat and friction is essential for optimal performance.

Features of Double-Row Full-Complement Cylindrical Roller Bearings

High Load Capacity: Double-row full-complement cylindrical roller bearings have two rows of rollers, offering exceptional radial load-carrying capacity due to the increased contact area between rollers and raceways.
Moderate Axial Load Support: These bearings can accommodate moderate axial loads in addition to their strong radial load capabilities, making them suitable for applications with combined loading.
Alignment Flexibility: Similar to their single-row counterparts, double-row full-complement bearings can tolerate slight misalignments, helping to accommodate shaft and housing deviations.
Reduced Friction and Wear: Without cages, these bearings experience reduced friction and wear due to the absence of cage-to-roller interaction, leading to improved efficiency and extended bearing life.

These features make double-row full-complement cylindrical roller bearings suitable for demanding applications where both radial and axial loads are present.
