Super Precision Angular Contact Ball Bearings S7020 ACE/HCP4ADT

Super Precision Angular Contact Ball Bearings S7020 ACE/HCP4ADT

The S7020 ACE/HCP4ADT is a super precision angular contact ball bearing with a 100mm bore and 150mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 15502 lbf and operates smoothly at speeds up to 16250 RPM.

Its sealed design and grease lubrication ensure low maintenance, while the phenolic cage offers excellent durability. The 25° contact angle and matched arrangement (2 bearings << DT) provide stability under angular loads. This bearing is ideal for high-precision applications like machine tool spindles or robotics, where accuracy and speed are crucial. It works in temperatures from -30°C to 110°C and meets P4A tolerance standards. Weighing 2.37kg, it’s robust yet manageable for its size. Compatible with SKF bearings, it’s a reliable choice for replacements or upgrades in demanding environments.
