Mining operations face critical challenges with bearing failures—premature wear from rock dust, unexpected downtime due to poor load handling, and difficulty finding reliable replacements for specialized equipment. When your conveyor systems or crushers stop working, every minute of delay impacts production schedules and profitability.
The NN3019 TN9/SP double row cylindrical roller bearing addresses these challenges with its 60-64 HRC hardness rating, ensuring resistance to abrasion and fatigue in harsh mining conditions. Our ISO 9001 certified production processes guarantee consistent quality, while our extensive inventory of bearings—including this high hardness cylindrical roller bearing—supports same-day shipping for urgent replacement needs.
Designed as a separated, non-aligning bearing, this double row cylindrical roller bearing excels in applications with high axial loads and moderate radial forces common in mining machinery. Its brass or steel cage options provide stability at varying speeds, while clearance grades (C0-C5) allow customization to specific operating conditions, from tight tolerance crushers to heavy-duty conveyors.
The bearing's 60-64 HRC surface hardness—achieved through precision heat treatment—directly translates to extended service life by minimizing wear under heavy loads. The separated design enables easy mounting and dismounting, reducing maintenance time during equipment overhauls. Vibration grades Z1V1 to Z3V3 ensure smooth operation, critical for reducing noise and preventing secondary damage to adjacent components in mining equipment.
Choosing a low-quality mining machinery bearing may save upfront costs, but the hidden expenses of frequent replacements, unplanned downtime, and potential equipment damage far outweigh initial savings. This NN3019 TN9/SP bearing's robust construction aligns with ISO 281 fatigue life standards, reducing the likelihood of premature failure. Our commitment to supplying bearings that meet original equipment specifications ensures compatibility and performance, lowering your total cost of ownership over time.
All our bearings undergo rigorous dimensional, hardness, and surface finish testing to meet industry standards. We provide a warranty against manufacturing defects, with clear traceability of materials and production batches. Our global network allows us to source and supply not just this NN3019 TN9/SP bearing, but a comprehensive range of bearings from leading international and domestic brands, ensuring you have a single reliable supplier for all your mining equipment needs.
Whether you need a single replacement or bulk order for your mining machinery, we can provide competitive pricing and fast delivery. Share your exact requirements—including quantity and delivery location—and our technical team will confirm availability and assist with any compatibility questions.
