BUSHINGS

Bushings are the heart of an elevator chain, wearing on the inside from the chain pin and on the outside from the traction wheel/sprocket.

All Emery bushings are machined from a carburizing grade of alloy steel then deep case carburized to the greatest level in the industry.

A well heat-treated bushing takes time! For example, an ER864 bushing requires over 24 hours in heat treat to achieve Emery’s specifications. Chain manufacturers check the carburized parts for a case depth by sawing a cross-section and acid etching. This creates a visible black ring showing the depth to which the carbon has penetrated. This test does not tell how deeply the material has hardened out.

Emery conducts a secondary test to ensure that the case has hardened out to a minimum of 50 Rc 50% into the etched case. This is called the “effective” case depth.

EMERY ELEVATOR CHAIN PIN

Emery pins are machined from alloy steels (aircraft quality for ER864 and ER984), through hardened, and then induction hardened on computercontrolled machines.

All Emery pins are rotated as they pass through the induction-hardening coil, providing the most concentric cases available.

COMPETITIVE PIN

Most competitive pins are passed through induction coils without rotating. Due to uneven electric fields in these coils, a lop-sided pattern is created. This uneven pattern creates “thin patches” that can be more readily worn through. It also causes uneven stress distributions.

The result is a pin with less wear resistance or pins that fail from fatigue before their time.

Pins

SIDEBARS

Emery chain sidebars are precisely cut by a CNC controlled laser, unique to the chain industry. Other chain manufacturers still use old-fashioned punch presses to blank shapes from bars and punch holes for bushings and pins.

In addition, Emery sidebar holes are machined, giving these chains the smoothest hole finishes and most accurate pitch control.

Sidebars

Punch Press Hole

Even the best punch press tooling will create 10% - 20% break-out (average tooling will produce 25% or more). This means that up to 25% of the chain sidebar is not in contact with the pin or bushing!

Machined Hole

Machining produces the truest, straightest holes possible.
