Bearing Type: deep groove ball bearings domestic new models: 61915-RZ Domestic older models: 1160915K inside diameter (mm): 75mm (2.9528in) outside diameter (mm): 105mm (4.1339in) Width (mm): 16mm (0.6299in) Weight (KG): 0.355 basic static load rating (kN): 22.5 (2295.92KG) basic dynamic load rating (kN): 24.3 (2479.59KG) grease lubrication speed (r / min): 5600 Oil lubrication speed (r / min) : 6700 the most representative of the rolling bearing, widely used to bear radial load and axial load applied to high-speed, low noise, low vibration occasions within a pre-filled sealed bearings with steel dust cover or rubber seals the amount of grease bearing outer ring with snap ring or flange, which is easy to axial positioning, and easy installation of the maximum load bearing housing bearing the same size as a standard, but the inner and outer ring has a slot loading, increasing the number of ball improves rated load characteristics: 1, 2 high speed, high precision 3, noise and vibration 4, 5 main radial load, but also bear certain axial load 6, create a simple, low-cost major used to maintain frame: steel stamping cage (waveform, crown-shaped ... separate; S-shaped double row ...) copper alloy or phenolic resin cutting cage, synthetic resin forming cage main purposes: car: rear, transmission, electrical installations Electrical components: General Motors, other household appliances: instruments, internal combustion engines, construction machinery, railway vehicles, handling machinery, agricultural machinery, industrial machinery deep groove ball bearings deep groove ball bearings are the most common type of rolling bearings. The basic model consists of a deep groove ball bearing outer ring, an inner ring, a ball and a group holding structure into. Deep groove ball bearing type has two single and double row deep groove ball structure is also divided into two structures sealed box open, open means bearing structure without seals, sealed deep groove ball into dust seal and anti- oil seal. Dust sealed cover material for steel stamping, just play the dirt and dust from entering the bearing raceway supervision, anti-oil-for-contact seal, which can effectively prevent the grease inside the bearing spill. Single row deep groove ball bearing type code of 6, double row deep groove ball bearing code is 4. Its structure is simple, easy to use, is the production of the most common and most widely used class of bearings. Works deep groove ball bearings mainly take radial load, but also to support radial and axial loads. When the only radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial load, with angular contact bearings can bear large axial load, deep groove ball bearing friction coefficient is small, the limit speed is also high bearing type 1 single 2.
