Spline Shafts
Key Features:
Designed for mining machinery and heavy-duty transmission systems
External spline structure for stable torque transmission and reliable mechanical engagement
Made from 18Cr2Ni4WA material for high strength, toughness, and durability
Involute spline profile for smooth engagement and stable load transfer
20° pressure angle for standard industrial spline transmission
DIN 3962 Class 6 accuracy for improved transmission precision
Suitable for high-load and demanding operating conditions
Shaft dimensions, spline profile, material, and heat treatment can be customized according to drawings or samples
Custom manufacturing available based on customer technical requirements
