CG-309-FF Forklift Roller Bearings Features and Advantages
High load capacity: With a special structural design and heat treatment process, these bearings can withstand radial and axial loads of up to several tons.
Guiding Function: They facilitate lifting, extension, and rotation actions, ensuring that forklifts can smoothly complete various operational tasks.
Optimized Operation: These bearings reduce noise and vibration during operation, enhancing driver comfort and promoting increased work efficiency.
Wear Resistance: Made from high-strength materials and advanced manufacturing processes, they exhibit excellent wear resistance, extending the service life of the bearings.
Impact Resistance: They possess certain impact and vibration resistance, allowing stable operation even in complex working environments.
Application: Forklift roller bearings are widely used in logistics and warehousing, industrial vehicles, construction, agriculture, and other fields.
QIBR - CG-309-FF Forklift Roller Bearings Optimization
High-Performance Materials: Bearing materials are replaced based on different working conditions, such as GCr15, GCr15SiMn, and SUJ2.
Surface Heat Treatment: Heat treatments like carburizing, nitriding, and chrome plating are employed to enhance surface hardness and wear resistance.
Sealing Structure: Sealing structures are selected based on the working environment of the bearings, such as FKM seals for high temperatures, HNBR seals for low temperatures, and PTFE seals for corrosion resistance.
More customization: QIBR can optimize and improve bearings according to customer drawings and operational requirements.
QIBR - CG-309-FF Forklift Roller Bearings Quality Control
Dimension measurement: Various high-precision instruments are used to measure multiple dimensions of the bearings, with maximum precision reaching 0.001mm.
Rotation accuracy: A dial indicator measures small defects or deviations on the bearing surface, achieving a measurement precision of 0.001mm.
Hardness measurement: Surface hardness is measured using a hardness tester, with an accuracy of ±0.5HRC.
Metallographic analysis: Internal metallographic structure is analyzed using a professional metallographic microscope.
Geometric tolerance: A contour gauge measures the bearing's geometric shape and relative position.
Noise monitoring: A vibration meter monitors vibration during operation to obtain noise data.
Raw material control: Steel and parts are sourced from ISO 14001-certified suppliers, ensuring product stability while promoting sustainable development.
Features & benefits
Depending upon the design of the mast and fork carriage assembly, chain Guide Roller Bearings can be subject to very high radial and thrust loads, as well as high intermittent shock loads.
The outer ring is made of high-purity special high-quality bearing steel processed by high-speed forging + cold rolling process, and the raceway surface is carbonitrided.
