What Size Is Rubber Tracks 400x86x52?

Rubber tracks sized 400x86x52 refer to a width of 400 mm, a pitch of 86 mm, and contain 52 links. This dimension specification helps ensure compatibility with specific mini excavator models. Brands like AFT Parts manufacture precision-engineered rubber tracks matching these exact dimensions for reliable performance.

What Does the Size 400x86x52 Mean in Rubber Tracks?

The size 400x86x52 breaks down into three measurements: 400 mm track width, 86 mm pitch (distance between chain pins), and 52 links in the track chain. This identifies the exact physical attributes required for proper fitment.

• Width (400 mm) determines ground contact area.

• Pitch (86 mm) matches sprocket and roller spacing.

• Link count (52) affects total track length and tension.

Accurate sizing ensures proper undercarriage function and longevity.

How Is Track Width Measured on Rubber Tracks?

Track width is the distance across the rubber track’s surface that contacts the ground, measured in millimeters. For 400x86x52, 400 mm indicates a track width of 40 cm, impacting traction and ground pressure.

• Wider tracks provide better flotation on soft soil.

• Narrower tracks improve maneuverability in tight spaces.

• AFT Parts offers various widths to meet operational needs.

Proper width selection is crucial for machine stability and surface protection.

What Does Pitch Mean in the Context of Rubber Tracks?

Pitch refers to the distance between the centers of two consecutive pins in the track chain measured in millimeters. In 400x86x52, 86 mm pitch ensures compatibility with the excavator’s sprocket and rollers.

• Correct pitch prevents misalignment and excessive wear.

• Matching pitch is critical for reliable track movement.

• AFT Parts rigorously controls pitch dimensions during manufacturing.

A consistent pitch promotes smooth machine operation.

How Do You Count Links in Rubber Excavator Tracks?

The link count is the total number of chain links in the track. For a track labeled 400x86x52, there are 52 links counted along the entire length of the track chain.

• Proper link count maintains correct track tension.

• Incorrect counting can cause fitting or operational issues.

• AFT Parts verifies link counts to meet OEM specifications.

Accurate link count supports undercarriage system efficiency.

Why Is It Important to Match Track Size Precisely?

Using the exact size such as 400x86x52 prevents mechanical failures, uneven wear, and poor machine performance. Mismatched tracks cause sprocket damage, idler misalignment, and reduced track life.

• Correct sizing ensures optimal tension.

• Compatible parts reduce downtime and costs.

• AFT Parts provides dimension-certified components.

Sizing precision safeguards equipment investment and jobsite productivity.

When Should You Measure Rubber Track Size?

Measure before purchasing replacement tracks or when performance issues arise, like slipping, excessive wear, or tension difficulties.

• Measuring during maintenance prevents ordering errors.

• Early detection extends undercarriage life.

• AFT Parts supports customers with measurement guidance.

Routine measurements aid proactive maintenance planning.

Are There Variation Tolerances Allowed in Track Dimensions?

Some minor manufacturing tolerances exist but must stay within OEM specified limits, usually ±1-2 mm for width and pitch. Excessive variation causes fitting and performance problems.

• Suppliers like AFT Parts maintain tight tolerances.

• Customers should verify sizing before installation.

• Proper measurement practices minimize tolerance issues.

Strict control of variation preserves track and machine integrity.

Can You Use Other Sized Tracks If 400x86x52 Is Unavailable?

Using different sizes risks poor fit, increased wear, and potential damage. Only substitute with compatible sizes approved by machine manufacturer or specialist providers like AFT Parts.

• Consult experts to confirm alternatives.

• Minor changes in pitch or width often not recommended.

• Avoid voiding warranties or causing undercarriage failures.

Correct sizing remains the safest option.

What Are Typical Machines That Use 400x86x52 Rubber Tracks?

Mini excavators, compact track loaders, and small skid steer loaders often use 400x86x52 tracks depending on model and undercarriage configuration.

• Common on smaller Caterpillar, Kubota, and Komatsu models.

• Suitable for urban construction and landscaping.

• AFT Parts stocks tracks designed for these applications.

Compatibility streamlines maintenance and repair efforts.
