BMT Bearings’ quality Stud Type Track Rollers adopt reinforced outer ring structure and optimized internal design, specially tailored for long-term track contact, cam driving and linear motion working conditions. Different from ordinary guide bearings,our track rollers deliver continuous and stable operation in frequent contact with linear tracks, rails and cam mechanisms, featuring stronger structural stability and environmental adaptability.
They are widely applicable to multiple industrial fields, covering conveyor guide systems, automated packaging lines, textile machinery, glove production equipment, agricultural machinery, material handling systems, robotic transfer units and cam follower guide rail systems.
All products are forged from high-carbon chrome GCr15 bearing steel with stable mechanical properties and excellent wear resistance. For humid, corrosive and special industrial environments, stainless steel materials and customized corrosion-resistant coatings are optional to enhance environmental adaptability.
Adopting controllable integral heat treatment and professional raceway hardening technology, the bearings achieve balanced surface and core hardness, effectively resisting surface spalling, wear and structural fatigue failure caused by long-term track rolling. Precision surface grinding ensures smooth rolling contact and consistent product batch performance.
Featuring thickened, reinforced outer rings and an integrated stud structure, these track rollers deliver enhanced overall rigidity and strong resistance against track contact impact and side loads. They effectively avoid structural deformation and displacement during long-term heavy-duty operation, securing stable positioning and continuous running of automated industrial equipment.
Manufactured from premium GCr15 bearing steel with integral heat treatment and raceway hardening, the rollers achieve uniform hardness and outstanding surface fatigue resistance. Precision grinding minimizes rolling friction loss, delivering excellent wear resistance and extended service life under high-cycle continuous operating conditions.
Three seal types (open, shielded, double sealed) are available to adapt to diverse working environments. The double-sealed structure blocks dust, moisture and industrial debris while preventing grease leakage. Pre-filled with standard grease (high-temperature grease optional), the rollers support 24-hour continuous industrial operation reliably.
Strict dimensional tolerance control guarantees precise stud concentricity, stable radial clearance and high-accuracy raceways. Optimized internal structure reduces running vibration and noise, enabling low-noise, high-precision and stable linear motion for long-term operation of automated production and precision transmission equipment.
The precisely ground raceway ensures uniform rolling contact, achieving low-noise and high-stability linear motion. Multiple structural configurations including standard type, eccentric collar type and fully sealed type are available. The optimized internal clearance design of Stud Type Track Rollers adapts to high-frequency continuous operation, vibration and slight structural deviation of equipment, maintaining consistent rolling accuracy and operational stability in long-cycle industrial production.
