Mobile Clutches

These mobile clutch products are typically used on a variety of pumps. Available from Clutch Engineering, Ogura creates a wide range of mobile clutches that are flange mounted. Ogura uses a heavy duty forged machined pulley which is able to stand up to abusive applications. They also use a high-quality long-life grease which performs better than standard high temperature greases. Mounting to a pump bracket or direct mounting to a pump face are the most common applications for this product. These clutches consist of two major subassemblies: the field and the rotor/armature assembly.

Torque range: 58 to 1,500 lb-ft (78 to 2,033 Nm)
Typical applications: Hydraulic pumps, water pumps, compressor/vacuum pumps

PTO Clutch/Brakes

Ogura PTO clutches and brakes from Clutch Engineering are pre-adjusted and easy to install. This takes less away from your downtime and further enhances your bottom line. Most models are a one-piece pre-set design, requiring no adjustments from the installers and operators. All PTO models conveniently use a special long-life grease which performs better than standard high temperature greases. Clutches can mount with a pulley facing toward or away from an engine. All Ogura one-piece clutches are adjusted at factory and no initial adjustment is required. As adjustable clutches wear, they can be re-gapped to extend the overall product life.

Torque range: 74 to 400 lb-ft (100 to 542 Nm)
Typical applications: Tractors, lawn care equipment

MMC Clutches

The MMC clutch has a compact design that can fit into available space more efficiently than larger alternatives. Ogura’s MMC electromagnetic clutches, provided by Clutch Engineering, do not require alignment or maintenance. These clutches are easy to mount, which reduces your downtime and further supports your bottom line. Efficient heat dissipation is a valuable feature of these MMC clutches that ensures a long service life. The complete unit consists of two major subassemblies: the rotor/field assembly and the armature. Out-of-box torque of these units is approximately 70% of the rated torque (requires burnishing for units to achieve rated torque).

Torque range: 37 to 1,475 lb-ft (50 to 2,000 Nm)
Typical applications: Packaging, printing, food processing, factory automation

MZ Clutches

Clutch Engineering offers MZ electromagnetic tooth clutches that can be used in either wet or dry applications. These MZ clutches from Ogura Clutch are able to efficiently transmit torque via teeth, meaning there’s no slip and minimal backlash within the system. This MZ series provides the highest torque per size of any electromagnetic clutch style. The entire unit consists of three major components: the field, the rotor and the armature/hub assembly. This unit can only engage at a low or zero rpm. It also varies with inertia and torque of the load. Generally, max engagement speed is 30rpm.

Torque range: 18 to 2,950 lb-ft (25 to 4,000 Nm)
Typical applications: Printing machinery, gear boxes, machine tools

RNB Brakes

These RNB brakes are a fail-safe option for your emergency braking needs in holding applications. Ogura Clutch RNB electromagnetic spring-applied brakes from Clutch Engineering can enhance the safety of your systems. RNB brakes come in 90VDC and 24VDC standard, but non-standard voltages are also available. The complete unit consists of two major subassemblies: the brake body, which includes the armature and friction disk, and the hub. These brakes are designed for holding applications only and are not meant for other dynamic braking applications.

Torque range: 1.5 to 148 lb-ft (2 to 200 Nm)
Typical applications: Robotics, machine tools, servo motors
