  • Mitutoyo 0-25mm Hub Micrometer 147-301

    Mitutoyo 0-25mm Hub Micrometer 147-301

    Product Overview

    The Mitutoyo 147-301 is a specialized Hub Micrometer (Series 147). While standard micrometers have a large, semi-circular frame that can get in the way, this unique tool features a very shallow throat depth and a reduced-profile frame.+1

    This design allows the micrometer to enter inside bores and recesses to measure:

    • Hub Thickness: The wall thickness of a hub or boss.
    • Shoulders: The length of a shoulder inside a bore.
    • Bearing Bushings: Checking the wall thickness of bushings where a standard micrometer frame would hit the outer wall.

    It features Carbide-Tipped measuring faces for durability and a Ratchet Stop for consistent measuring force. The 0-25mm range on this specific model means it can be zero-set by closing the faces (no standard bar required).

    Condition

  • Radius Master 8″ Drive Wheel – Old Style

    Radius Master 8″ Drive Wheel – Old Style

    The 8″ / 203mm drive wheel is the largest and most critical wheel on the Radius Master belt grinder. As both the primary belt drive wheel and a large-radius grinding station, it carries significant workload in any active workshop. The Old Style designation refers to the hub geometry, bore, and rubber specification of the original Radius Master production run — earlier machines were built to a slightly different specification than the current Series 2, and fitting the wrong wheel will result in an incorrect fit or poor tracking performance.

    If your machine predates the current Series 2 production, this is the correct replacement wheel. The Old Style Drive Wheel is manufactured to the same specification as the original factory-fitted part, ensuring a direct drop-in replacement with no machining or adaptation required.

    Like the current New Style wheel, the 8″ contact surface on older Radius Master machines is equally versatile: it serves as the primary belt drive point at the base of the head, and as a large-radius grinding station for primary bevel grinding, weld blending, radius work, and heavy stock removal. It also supports use of the Drive Wheel Tool Rest (RM-DWTR) and Hollow Grinding Jig (RM-HGJ) accessories.

    Signs your drive wheel needs replacing:

    • Belt slipping or surging under grinding load
    • Belt drifting despite tracking adjustments being correct
    • Vibration or roughness felt through the machine at belt speed
    • Visible flat spots, surface cracking, rubber separation, or glazing
    • Bearing roughness or play when spinning the wheel by hand
    • Uneven belt contact across the 50mm belt width

    Company Information

    This is a genuine spare part manufactured by NIROC, the Australian company that acquired Radius Master Machinery in 2025. NIROC maintains the full Radius Master spare parts catalogue — including both Old Style and New Style variants of the drive wheel — to support the entire Radius Master install base, from the earliest machines still running in workshops across Australia to current Series 2 production. All spare parts are engineered to original specification and backed by local Australian support.

    Important — confirm your machine variant before ordering. The Old Style and New Style drive wheels share the same external diameter but differ in hub geometry. If you are unsure which variant suits your machine, contact NIROC with your machine serial number before purchasing.


    Further Information

    How to Tell Old Style from New Style

    The easiest way to confirm which drive wheel your machine requires is to contact NIROC directly with your machine’s serial number. Alternatively, if you know your machine’s approximate age or production batch, NIROC can advise which variant is correct. As a general guide, machines produced before the current Series 2 revision will require the Old Style wheel.

    Fitting the incorrect wheel may result in improper seating on the drive shaft, incorrect belt alignment, or tracking instability — so it is worth confirming before ordering.

    Keeping an Older Radius Master Running

    One of the most compelling arguments for the Radius Master as a long-term workshop investment is the 20-year design life and the ongoing availability of genuine spare parts. Many Radius Master owners have machines that are 10, 15, or even 20+ years old and still producing excellent work. With genuine NIROC parts readily available, there is no reason these machines can’t continue in service for decades more. Replacing a worn drive wheel is one of the most effective ways to restore an ageing machine to like-new performance.

    Proactive Maintenance

    If your machine is several years old and due for a service, it’s worth inspecting the tracking wheel, belt tensioner, and platen assembly at the same time as the drive wheel — NIROC stocks all of these as individual spare parts.

  • Radius Master 89 x 50mm Tracking Wheel

    Radius Master 89 x 50mm Tracking Wheel

    The tracking wheel is a critical component in the Radius Master belt grinding system. Positioned at the top of the machine’s belt head, it works in conjunction with the tensioning and tracking adjustment mechanism to keep the 50 x 1220mm abrasive belt running true — centred, stable, and at consistent tension across all seven grinding stations.

    Over time and with heavy use, tracking wheels can develop flat spots, surface glazing, or bearing wear that causes belt drift, uneven tracking, or vibration. Replacing a worn tracking wheel restores the machine’s characteristic precision belt control — the same control that allows the Radius Master to reliably track stiff, heavy-duty polyester-backed ceramic belts that cause tracking problems on lesser machines.

    This replacement wheel measures 89mm in diameter x 50mm wide, matching the factory specification of the Series 2 belt head. Being a genuine NIROC/Radius Master part, it fits without modification and maintains the engineering tolerances the machine was designed around.

    Signs your tracking wheel may need replacement:

    • Belt drifts to one side despite tracking adjustments
    • Vibration or wobble at the top of the belt head
    • Belt wear pattern skewed to one edge of the belt
    • Visible flat spots, cracking, or glazing on the wheel surface
    • Bearing roughness or play when spinning the wheel by hand

    Further Information

    Genuine Parts vs. Aftermarket

    The Radius Master’s ability to track heavy ceramic-backed belts reliably depends on the rubber compound, wheel diameter, and bearing quality of the tracking wheel being within specification. Aftermarket or improvised replacements may use incorrect rubber hardness (durometer) that causes inconsistent belt tension — leading to belt wander, accelerated belt wear, or in worst cases, belt throw. Using genuine NIROC parts keeps your machine operating as designed.

    Servicing Your Radius Master

    If you are replacing the tracking wheel due to belt tracking problems, it’s also worth inspecting the tracking adjustment knob and tension spring for wear at the same time.
