Replacement Parts

CNC machining shops running production volumes on lathes rely on bar pullers to advance bar stock between parts without operator intervention. When a component wears, pull performance degrades, and in a high-volume run, that means interrupted cycles and added downtime. Accudyne Products manufactures the EZ-Puller line of American-made CNC bar pullers and stocks a full selection of replacement parts for every model, shipped same day from Englewood, CO.

BigEZ Replacement Parts

The BigEZ handles large-diameter bar stock and has three model-specific replacement components. The universal gripper pin and pivot pin sets (covered below) also apply to this model.

Available BigEZ bar puller replacement parts:

  • BigEZ Spring Kit, Standard Heavy Duty (95A), Set of 2 — $35.00. The 95A urethane spring is the correct choice for production runs involving steel and stainless steel.
  • BigEZ Spring Kit, Medium Duty (80A), Set of 2 — $35.00. The 80A covers aluminum and most general-purpose applications where a lighter grip force is the better fit.
  • BigEZ Polygon Gripper Kit — $209.00. Replaces the polygon-style grippers for hex, square, and other multi-sided bar profiles when wear affects pulling consistency.

If you are unsure which spring durometer matches your material, visit the product details and FAQ page for the full selection guide.

EZ-Puller & Expanded Capacity Replacement Parts

The standard EZ-Puller and EZ-Puller Expanded Capacity share the same replacement parts lineup. Four options cover springs and grippers for both models.

Available EZ-Puller bar puller replacement parts:

  • EZ-Puller Spring Kit, Standard Heavy Duty (95A), Set of 2 — $22.00. Designed for steel and stainless steel at full pull speed.
  • EZ-Puller Spring Kit, Medium Duty (80A), Set of 2 — $22.00. The most common choice for aluminum and general-purpose machining.
  • EZ-Puller Spring Kit, Light Duty (70A), Set of 2 — $22.00. Built for thin-wall tubing and delicate materials. Maximum pull speed: 100 IPM.
  • EZ-Puller Round Gripper Kit, Set of 2 — $142.00. Restores grip on round bar stock when the gripper surfaces show wear.

EZ-Puller and BigEZ Replacement Gripper Pin

The replacement gripper pin fits the EZ-Puller, EZ-Puller Expanded Capacity, and BigEZ. It comes as a set of 2 and is priced at $50.00.

The gripper pin holds the jaw assembly in position throughout the pull cycle. On high-volume production runs, this pin carries a consistent mechanical load. Replacing it at the first sign of play or resistance helps maintain pull performance and prevents secondary wear on surrounding components. Ordering a set of 2 covers both sides of the assembly and leaves a spare on hand for the next service interval.

EZ-Puller and BigEZ Replacement Pivot Pin

The replacement pivot pin also fits all three EZ-Puller model variants. Like the gripper pin, it comes as a set of 2 and is priced at $40.00.

The pivot pin controls the rotational movement of the jaw during bar engagement. When the pin wears, jaw travel becomes inconsistent, and the puller may fail to seat the bar cleanly. Catching pivot pin wear early prevents misfeed errors that would otherwise interrupt an unattended production run. Keeping a set of 2 on the shelf means maintenance does not wait for a parts order.

Replacement Parts FAQs

Finding the right bar puller replacement parts comes down to knowing your model and your material. The answers below cover the most common ordering questions.

Which replacement parts fit my EZ-Puller model?

The gripper pin and pivot pin are universal across the EZ-Puller, EZ-Puller Expanded Capacity, and BigEZ. Spring kits and gripper kits are model-specific. Match your puller to the correct product category above before ordering.

How do I choose the right spring durometer?

Three durometers are available: 95A for steel and stainless steel, 80A for aluminum and general use, and 70A for thin-walled and delicate materials, with a maximum of 100 IPM.

What is the lead time for bar puller parts?

All replacement parts ship the same day. Orders are assembled and fulfilled from Englewood, CO, and are typically shipped via FedEx the same business day.

How do I know when to replace springs or grippers?

Springs that no longer grip consistently, slip on familiar materials, or show visible deformation should be replaced. Grippers showing surface wear or dimensional change will reduce pulling accuracy. For pins, replace at the first sign of play or resistance in the jaw movement.
