Food Grade FluoroNyliner Bushing Bearings

Food Grade FluoroNyliner Bushing Bearings feature a non-magnetic 303 Stainless Steel corrosion resistant sleeve with a self-lubricating liner that is FDA and USDA compliant, enabling them to excel in challenging food processing applications. They are offered in Open and Closed types, with specific machining options available to satisfy unique application requirements. They feature robust liner material that can withstand a maximum continuous PV value of 10,000 psi ft./min., can handle high loads with a maximum static pressure value of 1,000 psi and provide maximum no load speeds to 400 ft./min. in temperatures ranging from -400°F up to 385°F. They are available in optional stainless steel pillow block assemblies in closed, open, flanged and twin styles, and can be combined with a range of corrosion-resistsant LinearRace® shafting options.

DC
Motor

The BI-05

Series slotless
brushless DC mo-
tor is designed for
maximum precision
and performance. The
slotless design eliminates
the magnetic cogging typi-
cally found in conventionally
wound “slotted” brushless
DC motors. The stator teeth
are completely eliminated by
forming and encapsulating the
entire stator winding along
the inside surface of the back
iron. The result is zero detent
torque, low inductance and
fast response rates. The body
measures a compact 0.5 in.

( 12. 7 mm) in diameter and is capable of no-load speeds up to 60,000 RPM. The miniature unit is rated for a continuous output torque rating up to 0.9 oz-in (0.0064 Nm). The construction is a combination of 17-4, 300 and 400 series stainless steels, the four-pole rotor is built using high-energy neodymium magnets, and an internal circuit board supports hall sensor feedback spaced at 120 electrical degrees.

Deep Groove Ball Bearings

MRC® brand HNCR deep groove ball bearings offer corrosion resistance to withstand
harsh operating conditions encountered in a variety of food and beverage processing
applications. These units are manufactured from high nitrogen corrosion resistant
steel (HNCR) to provide superior corrosion resistance, hardness and fatigue life com-
pared with standard 52100 or 440C stainless steel counterparts. The product
also integrates ceramic balls, stainless steel cages and stainless steel-
backed rubber seals to achieve full protection against corrosion on all
external and internal bearing surfaces. It offers extended service life
and improved reliability to help reduce downtime and maintenance
costs and promote enhanced uptime, productivity and profitability.

Shaft Grounding Ring Handbook

The AEGIS® Shaft Grounding Ring Motor Repair Handbook is a 36- page, color handbook which describes best practices for protecting motor bearings from electrical damage. The book explains how to diagnose electrical bearing damage caused by variable frequency drives (VFDs), also known as inverters. It also explains best practices for preventing such damage to motors of various sizes and horsepower ratings. Useful for plant maintenance personnel and motor repair shops, the book is available in a PDF format for downloading free of charge at www.est-aegis.com/bearing.
