21310-21314CCK W33 Self-Aligning Roller Bearings

Struggling with Bearing Reliability in Heavy-Duty Applications? The 21310-21314CCK W33 Self-Aligning Roller Bearings Deliver

Misalignment in industrial machinery creates excessive stress on bearings, leading to premature failure and costly downtime. Sourcing reliable self-aligning roller bearings that match original equipment dimensions while handling heavy radial loads often requires checking multiple suppliers—wasting valuable time that could be spent on production.

Engineered for Demanding Operating Conditions

The 21310-21314CCK W33 self-aligning roller bearings address these challenges through precision manufacturing and versatile design. Produced under ISO 9001-certified processes, these bearings accommodate shaft misalignment up to 2-3 degrees, making them ideal for applications like conveyor belt systems and construction equipment where perfect alignment is difficult to maintain. Our extensive inventory ensures quick access to this series, eliminating long lead times from traditional suppliers.

Optimal Performance in High-Load Environments

Designed to handle heavy radial loads with moderate axial capacity, these self-aligning roller bearings excel in低速 to medium-speed applications operating between -30°C and 120°C. The CCK design features a cylindrical bore with a tapered adapter sleeve, simplifying installation and removal in large equipment like mining crushers and steel mill rolls. Their ability to compensate for shaft deflection reduces uneven wear, extending service life in critical machinery.

Technical Features That Ensure Longevity

The W33 designation indicates a lubrication groove and three oil holes in the outer ring, facilitating efficient grease distribution for consistent performance. Constructed with high-carbon chromium steel, the bearings feature hardened raceways (HRC 58-62) and precision-ground rolling elements that minimize friction and vibration. The cage design maintains proper roller spacing even under shock loads, preventing skidding and premature fatigue. These engineering details translate directly to reduced maintenance intervals and lower total operating costs.

Por que a Seleção Adequada de Rolamentos Reduz o Custo Total de Propriedade

Choosing the right self-aligning roller bearing prevents hidden expenses associated with frequent replacements. A bearing with inadequate load capacity or misalignment tolerance can cause shaft damage, gear wear, and unexpected production stops—costing far more than the initial component price. By following ISO 281 fatigue life standards, these bearings provide predictable performance, allowing maintenance teams to plan replacements during scheduled downtime rather than emergency repairs.
