QUARRYING & MINING
NSK Bearings for the Quarrying & Mining Industries
NSK bearings offer Quarry and Mine operators longer service life under the most challenging operating conditions to maximise uptime and reduce maintenance costs for improved productivity at mining sites.
Durability and reliability are of paramount importance for mining machinery operating in remote locations such as mountains and deserts, where failure of a single component can impact the entire mining operation. NSK has applied state-of-the-art technology to exceed the life and limiting speed of conventional bearings.
We offer high performance bearings with robust design giving longer operating life, thereby reducing maintenance costs for mine operators.
Spherical Roller Bearings CAM-VS
Specifically engineered to withstand the harsh vibrating applications and tough working environments of the mining & quarrying industry. These bearings feature a one-piece machined brass cage and can accommodate varying degrees of misalignment. CAM-VS are specially designed to resist seizure and wear vibration, misalignment and shock load conditions.
HPS™ Spherical Roller Bearings
HPS series bearings are double-row self-aligning spherical roller bearings capable of carrying heavy radial loads with moderate axial loads in either direction. The spherical profile of the rollers, the inner ring raceway and the outer ring raceway, enable a self-aligning function that allows full capacity loading. The HPS series offers standard-size (steel-cage) and large size (brass cage) bearings with longer operating life and higher limiting speeds than conventional bearings.
Cylindrical Roller Bearings
By virtue of the line contact between rolling elements and raceways, these bearings have high radial load capacity and are suited to high-speed applications. With a patented high strength cage design in pressed steel, machined brass or polyamide, they offer low noise and heat generation and, for more arduous applications, can be supplied in a range of advanced special materials.
Mounted Units
NSK Bearing Units consist of a sealed single-row ball bearing with spherical outside diameter and extended inner ring mounted in a pillow block or flanged housing. The spherical fit accommodates initial misalignment. The NSK Bearing Units also feature ‘flingers’ that keep contaminants away from the bearing and improve the sealing performance. Housings are available in ductile cast iron, cast steel or stainless steel with a variety of shaft locking mechanisms.
