Roper Whitney 5212 Power Squaring Shear | 52" x 12 Ga Capacity | 1978 Mechanical

1978 Roper Whitney 5212 Power Squaring Shear

52" Cutting Length | 12-Gauge Capacity | Heavy-Duty Mechanical Drive

The Roper Whitney 5212 is a legendary American-made mechanical shear designed for high-speed, precision production. Built during an era of "over-engineered" industrial machinery, this 1978 model features a massive cast-iron frame and a high-torque mechanical drive that provides a cleaner, faster cut than most modern hydraulic equivalents in the same class.

Key Features & Machine Highlights

• High-Speed Mechanical Action: At 76 strokes per minute, this shear is significantly faster than hydraulic models, allowing for high-volume throughput without the "dwell time" common in hydraulic systems.
• Precision Hold-Down System: Equipped with multiple self-leveling hold-down feet that secure the sheet immediately before the cut, preventing material creep and ensuring a perfectly square edge.
• 4-Edge High-Carbon Blades: Features premium 4-edge blades that can be rotated to provide four times the service life between sharpenings.
• T-Slotted Table: The heavy-duty work table includes T-slots for easy integration of squaring arms and front support extensions.
• Electric Foot Pedal: Modernized with an electric foot switch for safe, hands-free operation from various positions along the front of the machine.
• Compact Industrial Footprint: Despite its heavy-duty 3,300 lb weight, the 5212 maintains a manageable footprint, making it ideal for job shops and production facilities alike.
