公司名称] established in 1921, is a diversified provider of industrial-use products and services. While remaining an international leader in the field of construction and mining equipment, Pioneer Machinery engages in other businesses, such as utility equipment (compact machines), forest machines, industrial machinery, logistics and other solutions-based operations. By upholding "Quality and Reliability" as the most important management policy, Pioneer Machinery is resolutely committed to providing safe, innovative products and services that best meet the needs and expectations of its customers around the world.Pioneer Machinery provide a wide array of construction and mining equipment, ranging from super-large machines capable of mining applications to mini units for urban use. Our range also includes a huge variety of attachments, along with system products. If the Bearing 71919 CD/HCP4AH1 SKF is not to be used immediately, it should be stored in a clean, dry place which is vibration free. Temperature should be stabilised to -20°C to +40°C. Eyebolts and/or lifting trunnions supplied with the Bearing 71919 CD/HCP4AH1 SKF should be screwed down until its shoulder is firmly against the face of the stator frame to be lifted. Eyebolts are normally designed for a vertical lift. Where two eyebolts are used with inclined loading, the maximum safe working loads of the table on page 10 (approximate weights) should not be exceeded.
