High Temperature Resistant Bearings

High Temperature Resistant Bearings are specifically engineered to deliver reliable operation, maximum durability, and precise rotation under extreme operating temperatures ranging from 150°C to over 500°C (300°F to 930°F). Standard bearings fail in high-heat environments due to grease degradation, structural deformation, and clearance loss. Our heat-resistant bearings overcome these challenges using specialized heat treatment processes, advanced high-temp lubricants, or solid-lubricated graphite cages.

Product Overview

Available in Chrome Steel, Stainless Steel, and Full Ceramic (Silicon Nitride / Zirconia) materials, these bearings are ideal for industrial ovens, kilns, heat treatment equipment, and metallurgical applications worldwide.

Key Features & Advantages

High Temperature Stability: Specially heat-treated rings and rolling elements prevent dimensional changes, micro-structural degradation, and thermal deformation during continuous high-temperature operation.

Advanced Heat-Resistant Lubrication: Equipped with high-performance synthetic high-temp grease, solid lubricants, or segmented graphite cages engineered for dry-running environments where conventional oils fail (temperatures up to 500°C+).

Increased Internal Radial Clearance: Precision-manufactured with expanded radial internal clearances (C3, C4, or C5) specifically designed to compensate for thermal expansion and prevent bearing lockup under extreme thermal gradients.

Superior Oxidation & Corrosion Resistance: Features advanced surface passivation, manganese phosphate anti-corrosion coatings, or optional stainless steel/ceramic materials to eliminate surface oxidation, flaking, and chemical degradation at elevated temperatures.

Extended Operational Lifespan & Reduced Downtime: Delivers exceptional reliability and reduced maintenance intervals in high-heat production environments, minimizing unscheduled line shutdowns and total cost of ownership.
