O.S. Walker Inc., NEO Permanent Lifting Magnets
NEO-1000 LIFTING GUIDELINES
(ROUND BARS & PIPES)
Values shown are for maximum rated capacities when operating instructions and warnings are
followed.
VALUES ARE BASED UPON AISI 1020 STEEL
Higher alloy steels and other magnetic materials will require further reductions of these rated
capacities (See page 11 for the Guidelines for the reduction of the Rated Lifting Capacities.)

NEVER LIFT ROUND BARS OR PIPES WITH:
A diameter LESS THAN 3 Inches or
A diameter GREATER THAN 11 Inches or
A wall thickness LESS THAN 3/8” (9.5 mm) or
A length greater than shown in the Lifting Guidelines above
(Absolute maximum length 177” (4500mm)
† Air Gap = nonmagnetic separation between magnet’s lifting surface and load.
