Inch Extins

Miniature bearing types with extended inner ring

They are designed for special applications. These bearings are easier to fit wider inner rings without the need for shims or washers. Typically, extended inner ring ball bearings or wide inner ring bearings are specifically designed to replace applications requiring additional locating flanges. AUB has full size extended inner ring ball bearings available. AUB's extended inner ring ball bearings are available in open type, with dust cover or with rubber seals, grades from ABEC-1 to ABEC-7 are available upon request. It can be widely used in medical equipment, cryogenic engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery and other fields.

Miniature bearing types with extended inner ring: radial, angular contact, full complementary, thrust.

• Radial miniature extended inner ring bearings can withstand extremely high radial loads and small amounts of axial loads.
• Angular contact widened inner ring bearings poate rezista la sarcini radiale și axiale extrem de mari.
• Full Ball extended inner ring bearings are characterized by lower limiting speeds but can withstand the highest loads.

Materiale: Chrome steel, stainless steel, ceramic hybrid, plastic

• Chromium steel is the most commonly used material for extended inner ring ball bearings because of its high load carrying capacity and low noise.
• When rust protection is required, 440c stainless steel material is usually used. This stainless steel material can withstand both high loads and high speeds. In addition, it has anti-rust function. Stainless steel miniature bearings with extended inner rings have stainless steel cages and suitable high temperature lubricants and can be used at constant temperatures up to 250°C or intermittently up to 300°C.
• Above these temperatures, the load-carrying capacity of stainless steel is reduced, so we recommend the use of all-ceramic bearings above 300°C. These bearings are suitable for mildly corrosive environments as the steel is corrosion resistant but will be affected by sea water and strong acids or bases.

Sealing and protection of miniature bearings

Majoritatea rulmenților miniaturali din oțel cromat de la AUB sunt disponibili ca Open sau cu scuturi metalice (Z sau ZZ). Dimensiuni mai mari sunt disponibile cu garnituri de contact din cauciuc sau PTFE (RS sau 2RS) sau garnituri din cauciuc fără contact cu frecare redusă (RZ sau 2RZ). Rulmenții deschisi sunt lubrifiați cu ulei ușor. Rulmenții ecranați sau etanșați sunt de obicei lubrifiați cu grăsime, dar rulmenții ecranați sunt disponibili cu ulei pentru instrumente pentru aplicații cu viteză mică și frecare redusă. Datorită unității noastre interne de relubrifiere, acești rulmenți miniaturali pot fi furnizați cu ulei, grăsime sau lubrifiant uscat specificat de client.
