Long Working Life GCR15 Steel 1300 Series Self-Aligning Ball Bearings (Models: 1304, 1305, 1306, 1310) are designed for high durability and performance in demanding applications. Made from GCr15 bearing steel, these bearings offer exceptional hardness, wear resistance, and fatigue strength, ensuring extended service life under heavy loads and high-speed conditions[3]. The self-aligning design compensates for shaft misalignment, reducing friction and operational stress.

The GCR15 Steel 1300 Series (1304, 1305, 1306, 1310) self-aligning ball bearings feature:
Model | Bore Diameter (mm) | Outer Diameter (mm) | Dynamic Load Rating (kN) |
---|---|---|---|
1304 | 20 | 52 | 15.8 |
1305 | 25 | 62 | 20.3 |
1306 | 30 | 72 | 25.1 |
1310 | 50 | 110 | 48.5 |
Optimized for:
Critical maintenance considerations:
Case 1: Paper Manufacturing
Replaced tapered rollers in dryer sections, reducing downtime by 40% through better thermal expansion accommodation.
Case 2: Cement Production
Implemented 1310 bearings in rotary kilns, achieving 18-month service life vs. previous 9-month average.
Zhengzhou Mining Group (2024)
Challenge: Frequent bearing failures in inclined conveyor systems (48° slope).
Solution: Installed 1305K bearings with conical bores[7].
Result: 62% reduction in replacement frequency, 17% energy savings.
Guangdong Paper Co., Ltd (2023)
Challenge: Thermal misalignment in Fourdrinier machines.
Solution: Upgraded to 1306ATN bearings with nylon cages[7].
Result: 850+ hours of continuous operation between maintenance cycles.
