Pin Coupling Types

Compare pin coupling families, published ratings and shaft interfaces before choosing a model.

Pin coupling types are organized by torque-transfer structure rather than by a long flat list of model names. The four product families below lead to eight published series. Use the family description first, then compare the exact size row for torque, speed, bores and dimensions.

Four product families

Elastic Pin Couplings

Elastic pin couplings use circumferential pins and elastic elements to transmit torque while moderating shock between connected shafts.

Elastic Sleeve Pin Couplings

Elastic sleeve pin couplings place a compliant sleeve around the pins, giving the connection a defined elastic interface for offset compensation and shock absorption.

Elastic Pin Gear Couplings

Elastic pin gear couplings use a jacket-and-pin torque path and are available in cylindrical-bore and conical-bore configurations in the selected range.

Brake Wheel Pin Couplings

Brake-wheel pin couplings integrate the shaft coupling with a coaxial brake wheel, creating a compact interface for drive systems that also require braking hardware.

HC, TC and ZC as structural reference points

HC is the standard elastic pin reference, TC is the elastic sleeve pin reference and ZC is the elastic pin gear reference. Brake-wheel variants extend these concepts where braking hardware must be integrated. GTC expands the sleeve-pin range into a much larger published family, while ZCD adds a conical shaft-hole option.

Selection by torque, speed and shaft interface

A family-range table is only the beginning. The proposed size must pass all three gates in the same published model row: torque, allowable speed and shaft-hole configuration. Then overall dimensions and maintenance access are checked against the machine. This is why a quotation should follow configuration review rather than a universal online price.

Brake wheel and conical bore options

HCL, TCL and ZCL address brake-wheel configurations. ZCD is the conical shaft-hole version of the pin gear family. Both options demand more interface information than a generic shaft diameter. Send the brake geometry or taper drawing when those configurations are being considered.

From product family to RFQ

Use the selection workflow to prepare the technical inputs, review application guidance for duty-specific questions, then send the RFQ with the shaft drawing when available.
