Product Description
LLA metallurgical equipment tire type coupling Specification: LA1-11 Nominal torque: 10-20000 Allowable speed: 5000-800 Shaft hole diameter: 5-180 Shaft hole length: 14-302 Weight: 0.35-373kg Material: cast iron Cast steel, suitable for wet, dusty, impact, vibration, changeable forward and reverse rotation and frequent starting working conditions, and easy disassembly, no lubrication, durable and reliable.
The main models of tire couplings are: UL tire coupling, LLB tire coupling, LLA tire coupling, DL polygonal rubber coupling, LAK saddle block elastic coupling, etc. UL type, LLB type and LLA type are the most commonly used models. Let's focus on the characteristics of these couplings: UL type tire coupling specifications mainly include UL1-18, nominal torque: 10-25000, allowable speed: 5000-800, shaft hole diameter: 11 -180mm, shaft hole length: 22-302mm, weight: 0.7-818, material: 45# round steel, cast steel, forged steel. UL tire coupling has good shock absorption and buffering performance, which solves the buffering effect that ordinary couplings cannot achieve.
