Shenyang Sanland Mining Engineering Co., Ltd. has successfully completed the final inspection and loading of a 7-foot cone crusher mainshaft sleeve, which is now on its way to the customer’s site. The product shown in the photo is the actual sleeve prepared for this shipment, securely packaged and ready for installation upon arrival.

The mainshaft sleeve is a critical protective component of a cone crusher’s main shaft. Its primary functions include isolating abrasive materials, absorbing operational impact, and preventing wear on the main shaft surface. As a key wear part, the quality and accuracy of the sleeve directly affect the crusher’s stability and service life. The 7-foot sleeve delivered this time is manufactured from high-strength wear-resistant alloy and processed through precision machining. Each unit undergoes strict dimensional inspection and assembly simulation to ensure excellent fit, durability, and operating reliability.
