POSI LOCK

POSI LOCK is a manufacturer of mechanical and hydraulic pullers, jaw sets, and related accessories for industrial maintenance and repair operations. The brand is known for its caged ram pullers, fan hub pullers, and replacement jaws, which are used in applications requiring the removal of bearings, gears, pulleys, and other press-fit components. POSI LOCK products are designed for use in workshops, manufacturing plants, and field service environments where controlled force application is necessary to avoid component damage. The product line includes mechanical jaw pullers with jaw spreads ranging from 1/4 in to 5 in and jaw reaches up to 4 in, as well as hydraulic puller systems with capacities from 10 tons to 100 tons. Hydraulic models are available with double-acting cylinders, electric pumps (115V AC), or two-speed manually operated pumps, and some include gauge adapters rated to 10,000 psi (690 bar). The brand also supplies spindle protectors and jaw head assemblies for specific model compatibility. POSI LOCK pullers are constructed with caged jaw designs that prevent jaw separation during operation, enhancing safety and repeatability. 3G Electric stocks over 140 SKUs of POSI LOCK products, including complete puller systems, individual jaw sets, and replacement parts, supporting global procurement for plant engineers and maintenance managers who require standardized tooling for bearing and shaft removal tasks.

Frequently asked questions

Common questions about POSI LOCK from 3G Electric.

What types of pullers does POSI LOCK manufacture?

POSI LOCK manufactures mechanical jaw pullers, caged ram pullers, fan hub pullers, and high-tonnage hydraulic puller systems. Mechanical models include caged external-grip jaw pullers with jaw spreads from 1/4 in to 5 in. Hydraulic models range from 10-ton to 100-ton capacity, with options for double-acting cylinders, electric pumps (115V AC), or two-speed manually operated pumps. The brand also produces replacement jaws and spindle protectors for specific puller models.

What is the maximum capacity of POSI LOCK hydraulic puller systems?

POSI LOCK hydraulic puller systems are available with nominal cylinder capacities up to 100 tons. For example, the PTPH-102TDA model is a 100-ton capacity high-tonnage hydraulic puller with a double-acting cylinder and an electric pump. Lower-capacity models include 10-ton and 15-ton caged ram pullers with two-speed manually operated pumps. All hydraulic systems are supplied with attachments and are rated for industrial use.

Are POSI LOCK pullers available with caged jaw designs?

Yes, many POSI LOCK pullers feature caged jaw designs. Caged jaws are standard on models such as the PMW-1 mechanical jaw puller set and the 104 caged external-grip jaw puller. The caged design prevents the jaws from spreading or detaching during operation, which improves safety and maintains consistent grip on the workpiece. This feature is common across both mechanical and hydraulic puller families.

What accessories does POSI LOCK offer for puller systems?

POSI LOCK offers replacement jaws, jaw head assemblies, spindle protectors, and gauge adapters. For example, the P6 spindle protector is compatible with PT106/PT206 models and protects the spindle tip during operation. The PTPHC-210 hydraulic ram puller includes a gauge adapter with a 10,000 psi (690 bar) gauge. Jaw head assemblies are available for specific models like the 110/210 and 11055.

What thread specifications are used on POSI LOCK mechanical pullers?

POSI LOCK mechanical pullers use thread specifications such as 9/16"-16, 3/8"-24, and 9/16"-16 x 9"-11/16, depending on the model. For example, the HP-2 fan hub puller has a thread spec of 9/16"-16 x 9"-11/16, while the PMW-1 jaw puller set uses 3/8"-24. These threads are designed to match standard industrial puller applications.
